Pololu MC33926 Motor Driver Carrier - PL-1212

Pololu MC33926 Motor Driver Carrier - PL-1212 info

Pololu MC33926 Motor Driver Carrier is a breakout board featuring two Freescale MC33926 H-bridge ICs. It can supply up to almost 3 A continuous current to a brushed DC motor at 5 – 28 V, and it can tolerate peak currents up to 5 A per channel for a few seconds, making Pololu MC33926 Motor Driver Carrier a great general-purpose motor driver for medium-sized DC motors and for differential-drive robots that use such motors. The MC33926 supports ultrasonic (up to 20 kHz) pulse width modulation (PWM) of the motor output voltage, which eliminates the audible switching sounds caused by PWM speed control, and a current feedback circuit for each motor outputs an analog voltage on its respective FB pin that is proportional to the output current.
