DRV8876 H-Bridge Motor Driver
Texas Instruments' drivers feature integrated current-sensing and current-sense output

Texas Instruments' DRV8876 flexible motor drivers are designed for a wide variety of end applications. The devices integrate an N-channel H-bridge, charge pump regulator, current-sensing and regulation, current proportional output, and protection circuitry. The charge pump improves efficiency by allowing for the high-side and low-side N-channel MOSFETs and 100% duty cycle support. The devices come in pin-to-pin, scalable RDS(on) options to support different loads with minimal design changes.

Integrated current-sensing allows for the driver to regulate the motor current during start-up and high load events. A current limit can be set with an adjustable external voltage reference. The DRV8876 devices provide an output current proportional to the motor load current. This can be used to detect motor stall or change in load conditions. The integrated current-sensing uses an internal current mirror architecture, removing the need for a large power shunt resistor which saves board area and reduces system cost.

A low-power sleep-mode is provided to achieve ultra-low quiescent current draw by shutting down most of the internal circuitry. Internal protection features are provided for supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent (OCP), and device overtemperature (TSD). Fault conditions are indicated on nFAULT.

Features
  • N-channel H-bridge
    • Drives one bidirectional brushed DC motor
    • Two unidirectional brushed DC motors
    • Other resistive and inductive loads
  • Operating supply voltage range: 4.5 V to 37 V
  • High output current capability: 3.5 A peak
  • Integrated current-sensing and regulation
  • Proportional current output (IPROPI)
  • Selectable input control modes (PMODE):
    • PH/EN and PWM H-bridge control modes
    • Independent half-bridge control mode
  • Supports 1.8 V, 3.3 V, and 5 V logic inputs
  • Selectable current regulation (IMODE): cycle-by-cycle or fixed off-time
  • Ultra-low-power sleep-mode: <1 µA at VVM = 24 V, TJ = +25°C
  • Spread spectrum clocking for low electromagnetic interference (EMI)
  • Integrated protection:
    • UVLO
    • CPUV
    • OCP
    • TSD
    • Automatic fault recovery
    • Fault indicator pin (nFAULT)
Applications
  • Brushed DC motors
  • Major and small home appliances
  • Vacuum, humanoid, and toy robotics
  • Printers and scanners
  • Smart meters
  • ATMs, currency counters, and EPOS
  • Servo motors and actuators
