Texas Instruments DRV8220 | Demoboard TIDA-010239

Beschreibung

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 our full portfolio of brushed motor drivers on ti.com.
