3 Description

The DRV8213 is an integrated motor driver with Nchannel

H-bridge, charge pump, current sense output,

current regulation, and protection circuitry. The tripler

charge pump allows the device to operate down to

1.65 V to accommodate 1.8-V supply rails and lowbattery

conditions. The charge pump integrates all

capacitors and allows for 100 duty cycle operation.

An internal current mirror implements current sensing

and regulation. This eliminates the need for a large

power shunt resistor, saving board area and reducing

system cost. The IPROPI current sense output allows

a microcontroller to detect motor stall or changes in

load conditions. The gain select (GAINSEL) feature

allows high accuracy current sensing down to 10

mA average motor current. Using the VREF pin,

this device can regulate the motor current during

startup and high-load events without interaction

from a microcontroller. The RTE package supports

sensorless motor stall detection and reporting to

microcontroller.

A low-power sleep mode achieves ultra-low quiescent

current by shutting down most of the internal circuitry.

Internal protection features include undervoltage

lockout, overcurrent, and overtemperature.
