DRV8835HB01B

Description

The DRV8835 provides an integrated motor driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion control applications. It features two H-bridge drivers capable of driving two DC motors or one stepper motor. The output driver block for each consists of N-channel power MOSFETs configured as an H-bridge. An internal charge pump generates gate drive voltages, and it includes protection features for overcurrent, short circuit, undervoltage lockout, and overtemperature.

The module can be used to control a stepper motor.

Features

  • Dual H-Bridge Motor Driver capable of driving:
    • Two DC Motors or
    • One Stepper Motor
  • Low MOSFET ON-Resistance: HS + LS 305 mΩ
  • 1.5-A Maximum Drive Current per H-Bridge
  • Bridges can be configured in parallel for up to 3-A Drive Current
  • Separate motor (0-V to 11-V) and logic (2-V to 7-V) supply pins
  • Flexible PWM or PHASE/ENABLE Interface
  • Low-Power Sleep Mode with 95-nA Maximum Supply Current

Applications

Ideal for battery-powered applications such as:

  • Cameras
  • DSLR Lenses
  • Consumer Products
  • Toys
  • Robotics
  • Medical Devices

Setup and Configuration

  1. Power Supply:
    • Ensure that the VCC is connected to a 2 V to 7 V supply.
    • Connect VM to a supply voltage between 0 V and 11 V depending on the required motor voltage.
  2. Input Configuration:
    • The default mode (IN/IN) is selected by setting MODE to low or leaving it unconnected.
    • Switch to PHASE/ENABLE mode by setting MODE to high.
  3. Sleep Mode:
    • Enter low-power sleep mode by setting all inputs to low (0 V).
