CG902 | 8 channel pyro fuse driver

5 Firing modes for optimum adaption to the pyro fuses

CG902 provides additional safety function for electrical systems in (H)EVs. Controlled by the battery management system, CG902 can ignite up to eight pyro fuses.

The pyro fuses safely disconnect the HV battery from the vehicle's electrical system. CG902 can also provide power to the battery management's microcontroller and monitor the microcontroller for proper function.

Benefits

Driver for up to four pyro fuses

High side & low side drivers for highest system safety

Power supply for system microcontroller

Target applications

HV battery safety disconnection in (H)EVs

Pyro fuse activation for HV isolation
