Description

The L99ASC03 is a multifunctional system IC

designed for three-phase motor control

applications.

The device features a voltage regulator to supply

an external microcontroller and an operation

amplifier for motor current sensing. It is designed

to control six external

N-channel MOSFETs in bridge configuration to

drive three-phase motors in automotive

applications. All gate driver outputs are controlled

by separate inputs.

The integrated Serial Peripheral Interface (SPI)

makes it possible to adjust device parameters,

control all operating modes and read out

diagnostic information.
