| FAN7842 High and Low Side Gate Driver February 2007 FAN7842 High and Low Side Gate Driver Features Floating Channels Designed for Bootstrap Operation to +200V Typically 350mA/650mA Sourcing/Sinking Current Driving Capability for Both Channels Common-Mode dv/dt Noise Canceling Circuit Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VCC=VBS=15V VCC & VBS Supply Range from 10V to 20V UVLO Functions for Both Channels TTL-Compatible Input Logic Threshold Levels Matched Propagation Delay Below 50ns Output In-phase with Input Signal 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.
