FAN7380
Half-Bridge Gate Driver
Features
Description
Floating Channel Designed for Bootstrapping
The FAN7380 is a monolithic half-bridge gate drive IC for
MOSFETs and IGBTs, which operate up to +600V.
Fairchild’s high-voltage process and common-mode
noise canceling technique give stable operation of 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
Operation to +600V
Typically 90mA/180mA 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
input logic level is compatible with standard TTL-series
logic gates. The internal shoot-through protection circuit
provides 100ns dead-time to prevent output switching
devices from both conduction during transition periods.
UVLO circuits for both channels prevent malfunction
when VCC and VBS are lower than the specified
VCC & VBS Supply Range from 10V to 20V
UVLO Functions for Both Channels
TTL-Compatible Input Logic Threshold Levels
Matched Propagation Delay Below 50ns
Built-in 100ns Dead-Time Control Function

threshold voltage. Output drivers typically source/sink at
90mA/180mA, respectively, which is suitable for
