The DRV8220 is an integrated
motor driver with four N-channel power FETs, charge pump regulator, and protection
circuitry. 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 DRV8220 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 DSG package supports an nSLEEP pin to
control sleep mode using a logic signal input.
The
device can supply up to 1.76 A of output current. It operates with a supply voltage
from 4.5 to 18 V.
The driver offers robust internal
protection features include supply undervoltage lockout (UVLO), output overcurrent
(OCP), and device overtemperature (TSD).
The DRV8220 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 information on the devices in this family. View
