专业电源管理 (PMIC) System Basis Chip, Linear 0.5A Vcore, FS1b, LDT, CAN, LQFP48EP

Safety Power System Basis Chip with CAN FD and LIN Transceivers

General description  MC33FS4503CAE

The FS6500/FS4500 SMARTMOS devices are a multi-output, power supply, integrated

circuit, including CAN Flexible Data (FD) and/or LIN transceivers, dedicated to the

automotive market.

Features  MC33FS4503CAE

• Battery voltage sensing and MUX output pin

• Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting buck-boost

and standard buck

• Family of devices to supply MCU core from 1.0 V to 5.0 V, with SMPS (0.8 A, 1.5 A or

2.2 A) or LDO (0.5 A)

• 36 V maximum input operating voltage

• Linear voltage regulator dedicated to auxiliary functions, or to sensor supply (VCCA

tracker or independent), 5.0 V or 3.3 V

• Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os supply (VCCA),

5.0 V or 3.3 V

Applications  MC33FS4503CAE

• Drive train electrification (BMS, hybrid EV and HEV, inverter, DCDC, alterno starter)

• Drive train - chassis and safety (active suspension, steering, safety domain gateway)

• Power train (EMS, TCU, gear box)

• ADAS (LDW, Radar, sensor fusion safety area)
