Product Description: WT7901 Monolithic Bridge Driver Power MOSFET by Weltrend

The WT7901 is a monolithic bridge driver power MOSFET for its driver stage. It is provided with forward, reverse, and brake functions and is ideal as a driver circuit for a motor that winds or rewinds the film in a camera.

The WT7901 is designed to operate from a single 5V supply voltage. It can drive a motor with a continuous current of up to 2A. The WT7901 also features a low-voltage drive (1.8V minimum), a thermal protection circuit, and a standby mode that turns off the charge pump circuit to conserve power.

The WT7901 is available in an SOP-8 package. It is a popular choice for driving small motors in a variety of applications, such as digital cameras, camcorders, and DVD players.
