MC33FS6522LAE

电源管理 (PMIC) System Basis Chip, DCDC 2.2A Vcore CAN LIN LDT, LQFP48EP

Safety Power System Basis Chip with CAN FD and LIN Transceivers

General description  MC33FS6522LAE

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.

Multiple switching and linear voltage regulators, including low-power mode (32 μA) are

available with various wake-up capabilities. An advanced power management scheme

is implemented to maintain high efficiency over a wide range of input voltages (down to

2.7 V) and output current ranges (up to 2.2 A).

Features  MC33FS6522LAE

• 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

• 3.3 V keep alive memory supply available in low-power mode

• Long duration timer, counting up to 6 months with 1.0 s resolution

• Multiple wake-up sources in low-power mode: CAN, LIN, IOs, LDT

• Five configurable I/Os

Applications  MC33FS6522LAE

• 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)
