55V – 3A Half-Bridge Power Driver Module
This Half-bridge module provides current measurement and regulation features for various loads. The module can be used to drive solenoids, Relays, Valves, DC-DC converters, Brushed DC motors, or other loads. It can operate from a 5V to 55V supply voltage and can deliver up to 3A of output current (depending on ambient temperature). Cycle-by-cycle current regulation, current limiting is adjustable using PR1 trimmer pot. Internal diagnostic and protection features include open-load detection, over-current protection (OCP), under-voltage lockout (UVLO), and thermal shutdown. The overcurrent limit is set to 3A and the retry time is 1.6mS. Solenoids can be controlled ON/OFF using Jumper J1. Use the PWM signal at the input pin for DC motor speed control.
Features
- Load Supply: Wide 5V to 55V Input Voltage Range
- 3A Maximum Output Current
- Cycle-by-Cycle Current Regulation/Limiting
- Adjustable Current Limit Using Trimmer POT
- On Board Power LED

- Fault Indication Output Logic Low Indicates Fault
- Low On-Resistance (High Side: 100mΩ (Internal Resistor Chip)
- Low Side: 120mΩ) (Internal Resistor Chip)
- No Control Power Supply Required
- Simple, Versatile Logic Interfaces
- Inputs Compatible with 2.5V, 3.3V, and 5V Logic
- Over-Current Protection (OCP), Trip Level 3Amps, Retry Time 1.6mS
- Open-Load Detection
- Thermal Shutdown, Threshold 165 Degree Cent. (Thermal shutdown hysteresis 15 Degree Cent.)
- Under-Voltage Lockout (UVLO), Threshold 4.1V
- PCB Dimensions 31.12 x 29.21mm
Connections and Other Details
- CN1: Pin 1 = Load Supply, Pin 2 = VCC, Pin 3 = Enable (High=Enable) , Pin 4 = PWM/Logic In, Pin 5 = Fault logic low if a fault condition (e.g. OCP, OTP, or open load occurs, Pin 6 = GND
- CN2: Pin 1 & 2 = Load Supply 5V to 55V DC, Pin 3 & 4 = GND
- CN3: Pin 1 & 2 = Load Output, Pin 3 & 4 = GND
- Jumper J1 = Internal Enable, Don’t Use this Jumper In case External Enable Input CN1 Pin 3 Required
- Jumper J2 = Output Direct Triger, Don’t Use this Jumper In Case External PWM Input CN1 Pin 4 Required
- D1: Power LED
- D2: Fault LED, Glow if a fault condition (e.g. over-current protection [OCP], over-temperature protection [OTP], or open load) occurs
- PR1: Trimmer Potentiometer to Set the Current Limit
