Product Introduction

Overview

The DRV8872-Q1 device, produced by Texas Instruments, is a brushed DC (BDC) motor driver designed for various automotive applications. It is AEC-Q100 qualified, ensuring its suitability for automotive environments with an ambient operating temperature range of –40°C to +125°C. The device is optimized for driving brushed DC motors, stepper motor windings, or other loads, and it features a wide operating voltage range of 6.8-V to 45-V. It is particularly useful in infotainment systems, HUD projector adjustments, motorized shifter knobs, and piezo horn drivers.

Key Features

  • H-Bridge Motor Driver: Drives one DC motor, one winding of a stepper motor, or other loads.
  • PWM Control Interface: Allows for pulse-width modulation to control motor speed.
  • Integrated Current Regulation: Limits motor current based on an external sense resistor.
  • Low-Power Sleep Mode: Enters sleep mode when both inputs are low, reducing power consumption.
  • Fault Status Output Pin (nFAULT): Reports fault conditions such as undervoltage, overcurrent, and thermal shutdown.
  • Integrated Protection Features: Includes VM undervoltage lockout (UVLO), overcurrent protection (OCP), thermal shutdown (TSD), and automatic fault recovery.
  • Small Package and Footprint: 8-Pin HSOP with PowerPAD™, measuring 4.9 × 6 mm.

Applications

  • Automotive Infotainment: Used in various infotainment systems.
  • HUD Projector Adjustment: Drives motors for head-up display projector adjustments.
  • Motorized Shifter Knobs: Controls motors in motorized shifter knobs.
  • Piezo Horn Drivers: Drives piezo horn drivers in automotive systems.
