Product Description
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 6.5 V to 40 V voltage range and is efficient enough to deliver a continuous 21 A without a heat sink. Additional features of this second-generation (G2) driver include reverse-voltage protection along with basic current sensing and current limiting functionality.
- Operating voltage: 6.5 V to 40 V (absolute maximum)
- Output current: 21 A continuous
- Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
- PWM operation up to 100 kHz
- Current sense output proportional to motor current (approx. 20 mV/A; only active while H-bridge is driving)
- Active current limiting (chopping) with default threshold of 50 A (can be adjusted lower)
- Reverse-voltage protection
- Undervoltage shutdown
- Short circuit protection
Dimensions
- Size: 1.3″ × 0.8″
- Weight: 5.0 g. Without included connectors.
General specifications
- Motor channels: 1
- Minimum operating voltage: 6.5 V
- Maximum operating voltage: 40 V. Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 34 V, which leaves a safety margin for ripple voltage on the supply line.
- Continuous output current per channel: 21 A. Typical results with 100% duty cycle at room temperature.
- Current sense: 0.02 V/A
- Maximum PWM frequency: 100 kHz
- Minimum logic voltage: 1.8 V
- Maximum logic voltage: 5.5 V
- Reverse voltage protection?: Y
