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
Applications
Half- and Full-Bridge Converters
Current-Fed Push-Pull Converters
Synchronous Buck Converters
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 TTL-
series logic gates.
The UVLO circuits for both channels prevent malfunction
when VCC and VBS are lower than the specified thresh-
old voltage. Output driver current (source/sink) is typi-
cally 350mA/650mA, respectively.
