Description:
This Pololu high-power motor driver is a compact carrier board for the VNH2SP30 motor driver integrated circuits from ST. The board incorporates most of the components of the typical application diagram on page 8 of the VNH2SP30 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. (Only the VNH2SP30 and VNH5019 supports current sense; the current sense circuit might not be populated on the VNH3SP30 version of the board.) All you need to add is a microcontroller, or other control circuit, to turn the H-Bridge on and off.


In a typical application, the motor power supply is connected at the bottom of the board, the motor on the right side of the board, and the control connections to the left side of the board. The diagnostic pins can be left disconnected if you do not want to monitor the fault conditions of the motor driver chip. INA and INB control the direction of the motor, and the PWM pin turns the motor on or off. The current sense (CS) pin will output approximately 0.13V per amp of output current.

Features:

  • Operating voltage: 5V - 16V
  • Maximum PWM frequency: 20 kHz
  • MOSFET on-resistance (per leg): 19mΩ
  • Over-voltage shutoff: 16V minimum (19V typical)
  • Current sense: ~ 0.13V/A
  • Time to overheat at 20A: 36 s
  • Time to overheat at 15A: 150s
  • Current for infinite run time*: 14A
