20-V, 1.76-A H-bridge motor driver with auto sleep mode

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
