High Side Mosfet Driver

High side switches mosfet drivers.

High side mosfet driver.

The n channel power mosfets typically have one third the on resistance of p channel mosfets of similar size and cost. The high side drivers come with high side referenced output channels to control power devices like mosfets and igbts. A mosfet driver is a type of power amplifier that accepts a low power input from a controller ic and produces a high current drive input for the gate of a high power transistor such as an insulated gate bipolar transistor igbt or power mosfet. The device is internally protected from an overload condition by an active current limit and thermal shutdown.

Key features include wide input range of operation extended temperature range of operation a powerful gate drive and short circuit protection. The max1614 drives high side n channel power mosfets to provide battery power switching functions in portable equipment. Mosfet drivers are beneficial to mosfet operation because the high current drive provided to the mosfet gate decreases the switching time between the gate on off stages which leads to increased mosfet power and thermal efficiency. An internal micropower regulator and charge pump generate the high side drive output voltage while requiring no external components.

Mark as favorite the ncv8460a is a fully protected high side driver that can be used to switch a wide variety of loads such as bulbs solenoids and other accuators.
