3 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
