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.
