LTC4000 Controller
A high voltage, high current controller for battery charging and power management from Analog Devices
Analog Devices' LTC4000 is a high voltage, high performance controller that converts many externally compensated DC/DC power supplies into full-featured battery chargers.
Features of the LTC4000's battery charger include: accurate (±0.25%) programmable float voltage, selectable timer or current termination, temperature qualified charging using an NTC thermistor, automatic recharge, C/10 trickle charge for deeply discharged cells, bad battery detection and status indicator outputs. The battery charger also includes precision current sensing that allows lower sense voltages for high current applications.
Features
- Complete high performance battery charger when paired with a DC/DC converter
- Programmable input and charge current: ±1% accuracy
- Programmable C/X or timer based charge termination
- Instant-on operation with heavily discharged battery
- Wide input and output voltage range: 3 V to 60 V
- 28-Lead 4 mm x 5 mm QFN or SSOP packages
- Output ideal diode for low loss PowerPath™ and load sharing with the battery
- Input ideal diode for low loss reverse blocking and load sharing
- ±0.25% accurate programmable float voltage
- NTC input for temperature qualified charging
Applications
- High power battery charger systems
- High performance portable instruments
- Industrial battery equipped devices
- Notebook / subnotebook computers
