DRV8212 11-V H-Bridge Motor Driver with PWM, PH/EN, and Half-Bridge Control

Interfaces and Low-Power Sleep Mode

1 Features

3 Description

•

N-channel H-bridge motor driver

The DRV8212 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.

– MOSFET on-resistance: HS + LS 280 mΩ

– Drives one bidirectional brushed DC motor

– Two unidirectional brushed DC motors

– One single- or dual-coil latching relay

– Push-pull and bistable solenoids

– Other resistive, inductive, or LED loads

1.65-V to 11-V operating supply voltage range

High output current capability:

– Full-bridge: 4-A peak

– Half-bridge: 4-A peak per output

– Parallel half-bridge: 8-A peak

Multiple interfaces for flexibility and reduced GPIO

Standard PWM Interface (IN1/IN2)

Supports 1.8-V, 3.3-V, and 5-V logic inputs

Ultra low-power sleep mode

– <84.5 nA @ V_VM= 5 V, V_VCC= 3.3 V, T_J= 25°C

– Timed autosleep mode to reduce GPIO

Protection features

– Undervoltage lockout (UVLO)

– Overcurrent protection (OCP)

– Thermal shutdown (TSD)

Family of devices. See Device Comparison for

details.

– DRV8210: 1.65-11 V, 1 Ω, multiple interfaces

– DRV8210P: Sleep pin, PWM interface

– DRV8212: 1.65-11 V, 280 mΩ, multiple

interfaces

– DRV8212P: Sleep pin, PWM interface

– DRV8220: 4.5-18 V, 1 Ω, multiple interfaces

•

The DRV8212 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 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 DRV8212 is part of a family of devices which

come in pin-to-pin scalable R_DS(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
