L99ASC03G数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

The L99ASC03G 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.
