General Description
The FS5600 integrates a battery connected DC-DC controller with external FETs
and a battery connected DC-DC converter with internal FETs. It also offers functional
safety features such as independent voltage monitors, windowed watchdog timer, I/O
monitoring via ERRMON and FCCU, and built-in self-test.

– Buck Controller - External FETs - 900 mA gate drive - up to 15 A load capability
– Buck Regulator - Internal FETs - 3 A+ load capability
– ±2 % Output Accuracy
– 250 kHz to 3 MHz switching frequency
• High-efficiency PFM mode
• Safety Features:
– Available in Enhanced ASIL B, ASIL B, and QM variations
– 2 internal and up to 4 high-accuracy external voltage monitors
– Windowed Watchdog Timer
– ERRMON and FCCU monitoring
– 2 x PGOOD and 1 x FS0B outputs
– ABIST and LBIST for latest failure check
• GPIOs for seamless operation with PF PMICs
• Rated from –40 °C to 150 °C TJ
• 32-Ld 5 mm x 5 mm QFN
• AEC-Q100 Grade-1 Qualified

Applications
QM to ASIL D automotive applications such as:
• Infotainment / Cluster / Driver Awareness
• Telematics
• V2X
• Radar
• Vision
• ADAS
• Sensor fusion
Additional safety mechanisms may be needed for ASIL D compliance in the system level.
FS5600 is developed to meet ASIL B requirements.
