Overview
Description
The ISL94208 battery management IC is designed for use with a microcontroller and features an analog front-end with overcurrent protection for multi-cell Li-ion battery packs. The ISL94208 supports battery packs consisting of four to six cells in series and one or more cells in parallel.
The ISL94208EVZ evaluation board provides a platform to evaluate the performance of the ISL94208 battery front-end IC. The kit contains the following components:
- ISL94208EVZ board
- ISL94208DB1EVZ cell balance daughter board
- ISL94208DB2EVZ cell balance daughter board
- GUI software for a PC running Windows XP
- A power supply interface board for connecting a single power source or a battery stack
Features
- Software selectable overcurrent protection levels and variable protect detection times
- 4 discharge overcurrent thresholds
- 4 short-circuit thresholds
- 4 charge overcurrent thresholds
- 8 overcurrent delay times (charge)
- 8 overcurrent delay times (discharge)
- 2 short-circuit delay times (discharge)
- Automatic FET turn-off and cell balance disable upon reaching external (battery) or internal (IC) temperature limit
- Automatic cell balance turn off on IC over-temperature
- Integrated charge/discharge FET drive circuitry
- Internal cell balancing FETs handle up to 200mA of balancing current for each cell
- Sleep operation with negative or positive edge wake-up
- <10μA sleep mode
