Features and benefits

Operating modes

? Normal mode with all power management and functional safety features available

? Stop mode: Low-power OFF mode with multiple wake-up sources (LPOFF)

? Standby mode: Low-power ON mode with HVBUCK or HVLDO1 active and multiple wake-up sources (LPON)

Power management

? HVBUCK: Synchronous buck converter with integrated FETs. Configurable Normal mode output voltage and LPON mode output voltage

(3.3 V or 5.5 V). Output DC current capability of 600 mA in Normal mode, and 100 mA current capability in Low-power ON mode

? HVLDO1: High-voltage LDO instead of the HVBUCK for MCU supply with selectable output voltage (3.3 V or 5.5 V) and up to 100 mA

DC current capability with internal PMOS and 250 mA with external PNP

? HVLDO2: High-voltage LDO regulator for system loads, with optional external protection for off-board sensors, selectable output voltage

(3.3 V or 5.0 V) and up to 100 mA DC current capability

? HVLDO3: High-voltage LDO regulator for CAN FD block supply or other with selectable output voltage (3.3 V or 5.0 V) and up to 150

mA current capability

System features
