FAN7842 High and Low Side Gate Driver
Features
Floating Channels Designed for Bootstrap Operation
Description
The FAN7842, a monolithic high and low side gate drive IC, which can drive
MOSFETs and IGBTs that operate up to +200V. Fairchild’s high-
voltage process and common-mode noise canceling technique provide stable operation of the high-side driver under high-dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The input logic level is compatible with standard TTLseries logic gates. The UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold
voltage. Output driver current (source/sink) is typically 350mA/650mA, respectively.
