POLOLU HIGH-POWER MOTOR DRIVER 24V23 CS
POLOLU HIGH-POWER MOTOR DRIVER 24V23 CS
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The compact 1.8×1.2-inch board supports a wide 5.5 to 40 V voltage range and is efficient enough to deliver a continuous 23 A without a heat sink. This version outputs an analog voltage proportional to the motor current, and an extra control input allows for coasting in addition to the driving and braking offered by the other Pololu high-power motor drivers.
