Intersil - Multi-Cell Li-ion Battery Monitor for Hybrid and Electric Vehicle (HEV/EV) Applications
As part of its new HEV/EV system solution, Intersil today introduced a second device that provides a 12-channel automotive grade Li-Ion battery fault and safety monitor. To address the safety requirements of an HEV/PHEV(plug-in hybrid)/EV Li-Ion battery system, the ISL78601 provides independent and redundant fault monitoring when used in conjunction with the ISL78600 battery management system (also introduced today, see related news release).To a
As part of the system's safety features, the ISL78601 has extensive built-in fault detection for its internal functions and detects external faults such as over and under voltage. The device also includes a watchdog timer to detect communication failures.
The ISL78601 allows for easy connections to microcontrollers via either a 2.5MHz SPI or 400KHz I2C interface, and is specified for -40ºC to 105ºC operation.
