DRV8838 Single Brushed DC Motor Driver Carrier

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. The board ships populated with SMD components, including the DRV8838, and adds a FET for reverse battery protection.

Beschreibung

  • 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
