D1FP3-5103 is a 4-pin high-side type power MOSFET driver module made by Shindengen. It features 150V/6A DC output voltage, wide input voltage range from 4.5V to 6.0V, temperature protection, and built-in frequency oscillator for stable operation even under rough conditions. It has small size and low quiescent current, making it ideal for applications such as motor drivers, DC/DC converters, power supplies, inverters, and ECUs.
