Overview

The FAN7391 is a monolithic high- and low-side gate-drive IC, which can drive high-speed MOSFETs and IGBTs that operate up to +600 V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction.onsemi's high-voltage process and common-mode noise-canceling techniques provide stable operation of the high-side driver under high-dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS = -9.8V (typical) for VBS = 15V. The advanced input filter of HIN provides protection against short-pulsed input signals caused by noise.The UVLO circuits prevent malfunction when VDD and VBS are lower than the specified threshold voltage. The high-current and low-output voltage-drop feature makes this device suitable for the PDP sustain pulse driver, motor driver, switching mode power supply, and high-power DC-DC converter applications.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
