Pololu High-Power Motor Driver 24v12

The Pololu High-Power Motor Driver 24v12 is a discrete MOSFET H-bridge motor driver

enables bidirectional control of one high-power DC brushed motor.

This small sized 1.3x0.8-inch board supports a wide 5.5 to 40 V voltage range

Efficient enough to deliver a continuous 12 A without a heat sink.

Pololu High-Power Motor Driver 24v12 Specifications

Dimensions


Size:     1.3" x 0.8"
Weight:     2.8 g1


General specifications


Motor channels:     1
Minimum operating voltage:     5.5 V
Maximum operating voltage:     40 V
Continuous output current per channel:     12 A2
Maximum PWM frequency:     40 kHz3

Notes:

1    Without any connectors or through-hole capacitors.
2    Typical results with 100% duty cycle at room temperature. Continuous current can be as high as 18 A if the MOSFETs are kept cool with air flow or a heat sink.
3    Higher frequencies are possible, but duty cycle will be limited by dead time of approximately 3 μs per cycle.
