ISL78600 Functional Diagram
Description
The ISL78600 Li-ion battery manager IC supervises up to 12 series-connected cells. The part provides accurate monitoring, cell balancing, and extensive system diagnostics functions. Three cell balancing modes are incorporated: Manual Balance mode, Timed Balance mode, and Auto Balance mode. The Auto Balance mode terminates balancing functions when a charge transfer value specified by the host microcontroller has been met. The ISL78600 communicates to a host microcontroller through an SPI interface and to other ISL78600 devices using a robust, proprietary, two-wire daisy chain system. The ISL78600 is offered in a 64 Ld TQFP package and is specified for operation at a temperature range of -40°C to +105°C.
Applications
- Hybrid vehicle battery pack

- Application NotePDF 993 KB an1723 Dec 15, 2021AI-generated Summary: The document discusses troubleshooting voltage drops and faults in the ISL78600/ISL78610 battery management ICs, emphasizing checks on diodes, resistors, and EEPROM integrity. It explains the use of P-channel and N-channel FETs in cell balancing to optimize drive voltages and noise immunity. It addresses issues with manual balancing disabling during high current events due to power-on resets triggered by voltage glitches and suggests additional filtering. The auto balance system removes charge based on calculated State of Charge, using a balance value derived from cell voltage, resistance, and balance time. The document also covers CRC checksum usage in daisy chain mode.
- White PaperThe power FET is an essential safety function in a battery management system (BMS). The main purpose of the power FET is to isolate the battery pack from either a load or a charger in errant conditions. This white paper discusses the detection blocks and how they apply to the state of the power FETs to ensure safe operation of lithium ion (Li-ion) battery packs.
