L99ASC03G Multifunctional System IC

STMicroelectronics L99ASC03G Multifunctional System IC is a brushless/sensorless 3-phase motor pre-driver for automotive applications. The L99ASC03G features a voltage regulator to supply an external microcontroller and an operation amplifier for motor current sensing. The IC 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) can be used to adjust device parameters, control all operating modes and read out diagnostic information. Applications for the STMicroelectronics L99ASC03G Multifunctional System IC are Mechatronic three-phase motors such as engine cooling fans, fuel pumps, water pumps, and oil pumps.
