Pololu High-Power Motor Driver 18v15 info

Pololu High-Power Motor Driver 18v15 is a discrete MOSFET H-bridge designed to drive large DC brushed motors. The H-bridge is made up of one N-channel MOSFET per leg, and most of the board’s performance is determined by these MOSFETs (the rest of the board contains the circuitry to take user inputs and control the MOSFETs). The MOSFETs have an absolute maximum voltage rating of 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 Pololu High-Power Motor Driver 18v15 makes it suitable for a large range of currents and voltages: it can deliver up to 15 A of continuous current with a board size of only 1.3" by 0.8" and no required heat sink. With the addition of a heat sink, it can drive a motor with up to about 21 A of continuous current. The module offers a simple interface that requires as little as two I/O lines while allowing for both sign-magnitude and locked-antiphase operation. Integrated detection of various short-circuit conditions protects against common causes of catastrophic failure; however, please note that Pololu High-Power Motor Driver 18v15 does not include reverse power protection or any over-current or over-temperature protection.

Note: Batteries that are nominally 24 V can be much higher than that when fully charged; this product is therefore not recommended for use with 24 V batteries unless appropriate measures are taken to limit the peak voltage.
