FAN7190_F085 - High-Current, High & Low Side, Gate-Drive IC
May 2010
FAN7190_F085
High-Current, High & Low-Side, Gate-Drive IC
Features
Floating Channels for Bootstrap Operation to +600V
Typically 4.5A/4.5A Sourcing/Sinking Current Driving
Description
The FAN7190_F085 is a monolithic high- and low-side
gate-drive IC, which can drive high speed MOSFETs and
IGBTs that operate up to +600V. It has a buffered output
stage with all NMOS transistors designed for high pulse
current driving capability and minimum cross-conduction.
Fairchild’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 V
S
=-9.8V (typical) for V
BS
=15V.
The UVLO circuit prevents malfunction when V
DD
and
V
BS
are lower than the specified threshold voltage.
The high current and low output voltage drop feature
make this device suitable for magnetic- and piezo type
injectors and general MOSFET/IGBT based high side
driver applications

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. -40C <=T
A
<= 125C, unless otherwise specified.
