CG912
4 channel pyro fuse driver
Application & Technical Summary
CG912 provides additional safety function for electrical systems in (H)EVs. Controlled by the battery management system, CG912 can ignite up to four pyro fuses. The pyro fuses safely disconnect the HV battery from the vehicle’s electrical system. CG912 can also provide power to the battery management's microcontroller and monitor the microcontroller for proper function.
