Find Designs, Fast

About Reference Design Library

Instead of searching many manufacturer sites or calling on companies to find and compare designs, now you can search for designs based on the circuit’s performance using Digi-Key’s Reference Design Library.

The Reference Design Library was created in order to:

  • Save Engineers time
  • Deliver ideas, fast
  • Sift through designs based on performance
  • Provide designs conveniently accompanied by their schematics

Visit often as new designs are being added weekly and improvements will be made based on your constructive feedback.

DRV11873EVM: 1.5A, 3-Ph Brushless DC (BLDC), 5 ~ 16V

Manufacturer: Texas Instruments

The DRV11873EVM is a complete solution for evaluating the DRV11873 12-V, three-phase, sensorless BLDC motor driver. It includes a TLC555 timer configured to supply a PWM to the DRV11873, a potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM, a jumper on the FG pin to allow the use of an external pull-up resistor, and a jumper on the RD pin to indicate that the motor has entered a lock protection state.

DRV8838EVM: 1.8A H-Bridge, 1.8 ~ 11V In

Manufacturer: Texas Instruments

The DRV8838EVM is a complete solution for evaluating the DRV8838 low voltage brushed DC motor driver. It includes a MSP430 microcontroller that is pre-programmed to take input from an analog potentiometer, for PWM speed control, and a direction jumper, to change motor direction.

EVB_RT7237AHGSP: 3.3V @ 2A, 4.5 ~ 18Vin

Manufacturer: Richtek USA Inc.

The RT7237A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 18V input supply. The RT7237A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors.
