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
