3 Description

The TL331B and TL391B devices are the next

generation versions of the industry-standard TL331

comparator. These next generation devices provide

outstanding value for cost-sensitive applications, with

features including lower offset voltage, higher supply

voltage capability, lower supply current, lower input

bias current, lower propagation delay, wider

temperature range and improved 2kV ESD

performance with drop-in replacement convenience.

The TL331B is a drop-in improved replacement for

both the TL331I and TL331K versions, while the

TL391B provides an alternate pinout of the TL331B to

replace competitive devices.

Operation from dual supplies also is possible as long

as the difference between the two supplies is within 2

V to 36 V, and VCC is at least 1.5 V more positive

than the input common-mode voltage. Current drain is

independent of the supply voltage. The outputs can

be connected to other open-collector outputs to

achieve wired-AND relationships.

7 Detailed Description

7.1 Overview

The TL331 family is a single comparator with the ability to operate up to 36 V on the supply pin. This standard

device has proven ubiquity and versatility across a wide range of applications. This is due to its very wide supply

voltages range (2 V to 36 V), low Iq, and fast response.

The open-collector output allows the user to configure the output's logic low voltage (VOL) and can be utilized to

enable the comparator to be used in AND functionality.

The TL331B and TL391B are performance upgrades to standard TL331 using the latest process technologies

allowing for lower offset voltages, lower input bias and supply currents and faster response time over an

extended temperature range. The TL331B can drop-in replace the "I" or "K" versions of TL331. The TL391B is

an alternate pinout for replacing competitive devices.

7.3 Feature Description

TL331x family consists of a PNP Darlington pair input, allowing the device to operate with very high gain and fast

response with minimal input bias current. The input Darlington pair creates a limit on the input common mode

voltage capability, allowing TL331x to accurately function from ground to VCC – 1.5 V differential input.

The output consists of an open collector NPN (pull-down or low side) transistor. The output NPN will sink current

when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is

resistive and will scale with the output current. Please see Figure 6-3 for VOL values with respect to the output

current.

7.4 Device Functional Modes

7.4.1 Voltage Comparison

The TL331x operates solely as a voltage comparator, comparing the differential voltage between the positive

and negative pins and outputting a logic low or high impedance (logic high with pull-up) based on the input

differential polarity.

8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification, and TI

does not warrant its accuracy or completeness. TI’s customers are responsible for determining

suitability of components for their purposes. Customers should validate and test their design

implementation to confirm system functionality.

8.1 Application Information

TL331x will typically be used to compare a single signal to a reference or two signals against each other. Many

users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an

MCU or logic device. The wide supply range and high voltage capability makes TL331x optimal for level shifting

to a higher or lower voltage.

Input 0 V to 30 V

Figure 8-1. Typical Application Schematic

8.2.1 Design Requirements

For this design example, use the parameters listed in Table 8-1 as the input parameters.

Table 8-1. Design Parameters

DESIGN PARAMETER EXAMPLE VALUE

Input Voltage Range 0 V to VCC – 1.5 V

Supply Voltage 2 V to 36 V

Logic Supply Voltage (RPULLUP Voltage) 2 V to 36 V

Output Current (VLOGIC/RPULLUP) 1 µA to 4 mA

Input Overdrive Voltage 100 mV

Reference Voltage 2.5 V

Load Capacitance (CL) 15 pF

8.2.2 Detailed Design Procedure

When using TL331x in a general comparator application, determine the following:

• Input voltage range

• Minimum overdrive voltage

• Output and drive current

• Response time

8.2.2.1 Input Voltage Range

When choosing the input voltage range, the input common mode voltage range (V ICR) must be taken in to

account. If temperature operation is above or below 25°C the VICR can range from 0 V to VCC – 1.5 V. This limits

TL331, TL331B, TL391B

Product Folder Links: TL331 TL331B TL391B

I TEXAS INSTRUMENTS

the input voltage range to as high as VCC – 1.5 V and as low as 0 V. Operation outside of this range can yield

incorrect comparisons.

Below is a list of input voltage situation and their outcomes:

1. When both IN- and IN+ are both within the common mode range:

a. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current

b. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not

conducting

2. When IN- is higher than common mode and IN+ is within common mode, the output is low and the output

transistor is sinking current

3. When IN+ is higher than common mode and IN- is within common mode, the output is high impedance and

the output transistor is not conducting

4. When IN- and IN+ are both higher than common mode, the output is low and the output transistor is sinking

current

8.2.2.2 Minimum Overdrive Voltage

Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the

comparator over the offset voltage (VIO). In order to make an accurate comparison the Overdrive Voltage (VOD)

should be higher than the input offset voltage (VIO). Overdrive voltage can also determine the response time of

the comparator, with the response time decreasing with increasing overdrive. Figure 8-2 and Figure 8-3 show

positive and negative response times with respect to overdrive voltage.

8.2.2.3 Output and Drive Current

Output current is determined by the load/pull-up resistance and logic/pull-up voltage. The output current will

produce a output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use

Figure 6-3 to determine VOL based on the output current.

The output current can also effect the transient response. More is explained in the next section.

8.2.2.4 TL331B & TL391B ESD Protection

The "B" versions add dedicated ESD protections on all the pins for improved ESD performance. Please see

Application Note SNOAA35 for more information.

8.2.2.5 Response Time

Response time is a function of input over drive. See Section 8.2.3 for typical response times. The rise and fall

times can be determined by the load capacitance (C L), load/pullup resistance (R PULLUP), and equivalent

collector-emitter resistance (RCE).

• The rise time (τR) is approximately τR ~ RPULLUP × CL

• The fall time (τF) is approximatelyτF ~ RCE × CL

– RCE can be determined by taking the slope of Figure 6-3 in its linear region at the desired temperature, or

by dividing the VOL by Iout

9 Power Supply Recommendations

For fast response and comparison applications with noisy or AC inputs, it is recommended to use a bypass

capacitor on the supply pin to reject any variation on the supply voltage. This variation can eat into the

comparator's input common mode range and create an inaccurate comparison.

10 Layout

10.1 Layout Guidelines

For accurate comparator applications without hysteresis it is important maintain a stable power supply with

minimized noise and glitches, which can affect the high level input common mode voltage range. In order to

achieve this, it is best to add a bypass capacitor between the supply voltage and ground. This should be

implemented on the positive power supply and negative supply (if available). If a negative supply is not being

used, do not put a capacitor between the IC's GND pin and system ground.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation

of the previous line and the two combined represent the entire Device Marking for that device.

(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two

lines if the finish value exceeds the maximum column width.
