Low Side Gate Driver Ic

A gate driver is a 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 igbt or power mosfet.

Low side gate driver ic.

The pm8841 output can sink 1 a and source 0 8 a. Even if the n channel was being used in a low side configuration the driver chip would be needed to properly drive the gate fast enough. 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. Our portfolio spans a variety of configurations voltage classes isolation levels protection features and package options.

Our low side gate drivers feature high drive current low propagation delay negative voltage handling and under voltage lockout uvlo to maximize your system s performance and reliability regardless of application. Since the gate of the mosfet has to be v g s volts higher than the source a special ic is needed to translate the logic level at the ctl lead into the much higher gate voltage. A gate driver is a specially designed circuit that is used to drive the gate of mosfet or igbt in high side switching application. We offer excellent product families of galvanic isolated gate drivers automotive qualifies gate drivers 200 v 500 700 v 1200 v level shift gate drivers and non isolated low side drivers.

Now including the new 650 v high and low side silicon on insulator soi gate driver ics with high current 2 5 a and low current 0 7 a option. Our gate driver ic solutions are the expert s choice. 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. Gate drivers can be provided either on chip or as a discrete module.

We offer high and low side gate drivers with two non interlocked channels. Single channel low side gate driver the pm8841 is a high frequency single channel low side mosfet driver specifically designed to work with digital power conversion microcontrollers such as the stmicroelectronics stlux family of products. In essence a gate driver consists of a level shifter in combination with an amplifier.

With excellent ruggedness and noise immunity these gate drivers are perfect for motor drives home appliance smps battery powered applications and high power lighting. An integrated gate driver solution reduces design complexi. Featured low side driver devices ucc27511a.
