Pololu DRV8838 Single Brushed DC Motor Driver Carrier

Artikelnummer: PO2990

This tiny breakout board for TI?s DRV8838 motor driver can deliver a continuous 1.7 A (1.8 A peak) to a single brushed DC motor. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering a small, low-voltage motor. The carrier board has the form factor of a 10-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1? perfboards.

Overview

Texas Instruments? DRV8838 is a tiny H-bridge motor driver IC that can be used for bidirectional control of one brushed DC motor at 0 V to 11 V. It can supply up to about 1.7 A continuously and can tolerate peak currents up to 1.8 A for short durations, making it an ideal driver for small motors that run on low voltages. The DRV8838 is a great IC, but its small, leadless package makes it difficult for the typical student or hobbyist to use; our breakout board gives this driver the form factor of a 10-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1? perfboards. Since this board is a carrier for the DRV8838, we recommend careful reading of the DRV8838 datasheet (1MB pdf). The board ships populated with SMD components, including the DRV8838, and adds a FET for reverse battery protection.

Alternative driver options

This motor driver is essentially a smaller, lower-cost, single-channel alternative to our DRV8835 dual motor driver carrier and DRV8833 dual motor driver carrier, which have very similar operating voltage ranges and current ratings but offer an additional motor channel.

For higher-voltage alternatives to this driver, please consider our MAX14870, A4990, and DRV8801 motor driver carriers.

Features

  • H-bridge motor driver: can drive one DC motor
  • Motor supply voltage: 0 V to 11 V
  • Logic supply voltage: 1.8 V to 7 V
  • Output current: up to 1.7 A continuous (1.8 A peak); operation at low motor and logic supply voltages reduces the maximum continuous output current
  • PHASE/ENABLE interface (one pin controls direction and another controls speed)
  • Inputs are 3V- and 5V-compatible
  • Under-voltage lockout on the logic supply and protection against over-current and over-temperature
  • Reverse-voltage protection on the motor supply
  • Compact size (0.5?×0.4?) with the form factor of a 10-pin DIP package

Included hardware

Two 1×5-pin breakaway 0.1? male headers are included with the DRV8838 motor driver carrier, which can be soldered in to use the driver with breadboards, perfboards, or 0.1? female connectors. (The headers might ship as a single 1×10 piece that can be broken in half.) The right picture above shows the two possible board orientations when used with these header pins (parts visible or silkscreen visible). You can also solder your motor leads and other connections directly to the board.
