Description
The DRV8872DDARQ1 is a high-performance, automotive-grade brushed DC motor driver from Texas Instruments. It's designed for demanding applications such as power seats, mirrors, and window lifts in vehicles. This device features an H-bridge motor driver that can drive one DC motor or one winding of a stepper motor, with a peak current drive of 3.6A.
The DRV8872DDARQ1 operates over a wide voltage range of 6.8V to 45V and has a low RDS(on) of 565mΩ. It also features integrated protection mechanisms such as undervoltage lockout (UVLO), overcurrent protection (OCP), thermal shutdown (TSD), and fault reporting (nFAULT). These features enhance the device's reliability and safety in operation.
The DRV8872DDARQ1 is available in an 8-pin HSOP package with a small footprint of 4.9mm x 6mm, making it suitable for space-constrained applications. Its AEC-Q100 qualification ensures compliance with automotive industry standards for temperature range (-40°C to +125°C) and ESD protection (HBM level 2 and CDM level C4B).
