General description

The FS5600 integrates a battery connected DC-DC controller with external FETs and a

battery connected DC-DC converter with internal FETs. In addition, it offers functional

safety features such as independent voltage monitors, windowed watchdog timer, I/O

monitoring via ERRMON and FCCU and build-in-self-test.

Note: Electrical characteristics are maintained in the FS5600 data sheet
