POLOLU HIGH-POWER MOTOR DRIVER 24V12
POLOLU HIGH-POWER MOTOR DRIVER 24V12
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.3×0.8-inch board supports a wide 5.5 to 40 V voltage range and is efficient enough to deliver a continuous 12 A without a heat sink.
Dimensions
Size: 1.3" x 0.8"
Weight: 2.8 g
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
Maximum logic voltage: 5.5 V
MOSFET on-resistance (max per leg): 5 mΩ
Reverse voltage protection?: N
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.
