The DRV8872DDARQ1 is a single-channel H-bridge brushed DC motor driver from TI with integrated power MOSFETs, supporting 6.5V~45V wide input voltage range, 3.6A continuous output current, and 5A peak current. The device supports PWM speed control via IN1/IN2 logic input pins to achieve four operating modes: forward, reverse, brake, and standby.

DRV8872 integrates comprehensive protection: cycle-by-cycle overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO), ensuring safe and reliable operation under fault conditions. The chip also features current sensing via the ISENSE pin, enabling motor current monitoring without an external sense resistor.

The HSOP-8 package with exposed thermal pad provides effective heat dissipation, suitable for motor drive applications requiring sustained 3.6A output. The device meets automotive AEC-Q100 standard (Q1 suffix) and is suitable for automotive body electronics and industrial automation.

Note: Refer to the official TI DRV8872 datasheet for detailed electrical parameters. Subject to change without notice. Design engineers should verify all parameters before final design.

The DRV8872DDARQ1 uses HSOP-8 (8-pin with exposed thermal pad package) with 1.27mm pin pitch and a large exposed thermal pad on the bottom for improved thermal performance. The thermal pad should be soldered to a large PCB copper area with thermal vias for efficient heat dissipation. With sufficient PCB copper, the package can sustain 3.6A continuous drive.

The HSOP-8 package balances small size with high current capability, making it ideal for motor drive applications. The package meets RoHS directives, lead-free soldering requirements, and automotive AEC-Q100 reliability standards.
