FS4500 Safety power system basis chip

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.

FS4500 Features

* 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, 1.5 A or 2.2 A) or LDO (0.5 A)
