ATA6823C中文资料H-bridge Motor Driver and LIN System Basis Chip数据手册Microchip规格书

描述 Description

ATA6823C is designed for automotive body and powertrain applications. The IC is used to drive a continuous current motor in a full H-bridge configuration. An external microcontroller controls the driving function of the IC by providing a PWM signal and a direction signal and allows the use of the IC in a motor-control application. The PWM control is performed by the low-side switch; the high-side switch is permanently on in the driving phase. The VMODE configuration pin can be set to 5V or 3.3V mode (for regulator and interface high level). The window watchdog has a programmable time, programmable by choosing a certain value of the external watchdog resistor RWD, internally trimmed to an accuracy of 10%. For communication a LIN transceiver 2.1 is integrated.
