DRV8210中文资料具有自动睡眠模式的 12V、1.76A 有刷直流电机驱动器数据手册TI规格书

描述 Description

The DRV8210 is an integrated motor driver with four N-channel power FETs, charge pump regulator, and protection circuitry. The tripler charge pump architecture allows the device to operate down to 1.65 V to accommodate 1.8-V supply rails and low-battery conditions. The charge pump integrates all capacitors to reduce the overall solution size of the motor driver on a PCB and allows for 100% duty cycle operation.

The DRV8210 supports multiple control interface modes including: PWM (IN1/IN2), phase/enable (PH/EN), independent half-bridge, and parallel half-bridge. Each interface supports a low-power sleep mode to achieve ultra-low quiescent current draw by shutting down most of the internal circuitry.

The device can supply up to 1.76-A peak output current. It operates with a supply voltage from 1.65 V to 5.5 V.

The driver offers robust internal protection features include supply undervoltage lockout (UVLO), output overcurrent (OCP), and device overtemperature (TSD).

The DRV8210 is part of a family of devices which come in pin-to-pin scalable RDS(on) and supply voltage options to support various loads and supply rails with minimal design changes. See Device Comparison for information on the devices in this family. View our full portfolio of brushed motor drivers on ti.com.
