PRODUCT SPECIFICATION
FAN5056MV85
REV. 1.0.6 6/26/01
3
Absolute Maximum Ratings
Note 1: Component mounted on demo board in free air.
Recommended Operating Conditions
22
GNDP
Power Ground. Return pin for high currents flowing in pin 24 (VCCP).
23
LODRV
VCC Low Side FET Driver. Connect this pin to the gate of an N-channel MOSFET
for synchronous operation. The trace from this pin to the MOSFET gate should be
<0.5".
24
VCCP
Power VCC. For all FET drivers. Connect to system 12V supply through a 33Ω, and
decouple with a 1µF ceramic capacitor.
