DRV8212P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 DRV8212P 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 DRV8212P supports an industry standard PWM (IN1/IN2) control interface. The nSLEEP pin controls a low-power sleep mode which achieves ultra-low quiescent current draw by disabling the internal circuitry.

The device can supply up to 4-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 DRV8212P 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 Section 5 for information on the devices in this family. View our full portfolio of brushed motor drivers on ti.com.
