Pololu G2 High-Power Motor Driver 18v17

This is a Pololu G2 High-Power Motor Driver 18v17. The Pololu G2 high-power motor driver is a discrete MOSFET H-bridge designed to drive large brushed DC motors. The H-bridge is made up of one N-channel MOSFET per leg; the rest of the board contains the circuitry to take user inputs and control the MOSFETs. The absolute maximum voltage for this motor driver is 30 V, and higher voltages can permanently destroy the motor driver. Under normal operating conditions, ripple voltage on the supply line can raise the maximum voltage to more than the average or intended voltage, so a safe maximum voltage is approximately 24 V.

The versatility of this Pololu G2 High-Power Motor Driver 18v17 makes it suitable for a large range of currents and voltages: it can deliver up to 17 A of continuous current with a board size of only 1.3″ × 0.8″ and no required heat sink. The module offers a simple interface that requires as few as two I/O lines while still allowing for your choice of sign-magnitude or locked-antiphase operation. The power supply inputs feature reverse-voltage protection, while integrated detection of various fault conditions helps protect against other common causes of catastrophic failure; however, please note that the board does not include over-temperature protection.

Features:

1. Operating voltage: 6.5 V to 30 V (absolute maximum)
2. Output current: 17 A continuous
3. PWM operation up to 100 kHz
4. Current sense output proportional to motor current (approx. 20 mV/A; only active while H-bridge is driving)
5. Active current limiting (chopping) with default threshold of 40 A (can be adjusted lower)
6. Under voltage shutdown

Package Includes:

1 x Pololu G2 High-Power Motor Driver 18v17
