110V, 2.5A, SOIC-8, Single Channel Floating Gate Drivers with Desaturation Protection and Charge Pump

Favorite

Overview

The FAD3171MXA is a single channel floating automotive gate driver suitable for driving high−speed power MOSFETs up to 110V.  Designed in a SOI technology, the driver is ideal for applications that require noise immunity against severe negative
transients and ground offset up to −80 V. The FAD3171MXA driver has integrated desaturation detection to protect power switches during short−circuit and over−current conditions. The driver is also equipped with a soft shutdown feature, which initiates a soft shutdown of driver outputs upon desat detection, thus preventing possible overvoltage across power MOSFETs during a heavy−load condition.

The FAD3171MXA driver is equipped with bidirectional fault reporting pin that can generate a fault output during desat and under−voltage lockout (UVLO) condition. The bidirectional nature of the fault−reporting pin allows the driver to respond to external fault commands, thereby facilitating fault communication across the system. In addition, the FAD3171MXA has an integrated charge pump to support 100% duty cycle operation of high side MOSFETs.

In summary, the FAD3171MXA is a versatile driver with features like desat detection, soft shutdown, fault reporting capability, UVLO protection, and charge pump.  Designed to be used with the FAD3151MXA
