3 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
