HIP4082
80V, 1.25A Peak Current
H-Bridge FET Driver
Description
The HIP4082 is a medium frequency, medium voltage H-Bridge
N-Channel MOSFET driver IC, available in 16 lead plastic SOIC
(N) and DIP packages.
Specifically targeted for PWM motor control and UPS applica-
tions, bridge based designs are made simple and flexible with
the HIP4082 H-bridge driver. With operation up to 80V, the
device is best suited to applications of moderate power levels.
Similar to the HIP4081, it has a flexible input protocol for driving
every possible switch combination except those which would
cause a shoot-through condition. The HIP4082’s reduced drive
current allows smaller packaging and it has a much wider range
of programmable dead times (0.1 to 4.5
μ
s) making it ideal for
switching frequencies up to 200kHz. The HIP4082 does not
contain an internal charge pump, but does incorporate non-
latching level-shift translation control of the upper drive circuits.
This set of features and specifications is optimized for applica-
tions where size and cost are important. For applications need-
ing higher drive capability the HIP4080A and HIP4081A are
recommended.
