Description
Application Information
Positive gate drive supply
Decouple VDD to VSS using a low ESR/ESL capacitor, placed as
close to the IC as possible.
Connect the positive terminal of bootstrap capacitor to the HB pin
and connect negative terminal to HS. The Bootstrap capacitor
should be placed as close to IC as possible.
Connect to the gate of high side N-MOS device through a short,
low inductance path.
Connect to the negative terminal of the bootststrap capacitor and to
the source of the high side N-MOS device.

RDT
A resistor from RDT to VSS programs the turn-on delay of both the
high and low side MOSFETs. The resistor should be placed close
to the IC to minimize noise coupling from adjacent PC board traces.
TTL compatible threshold with hysteresis. LO and HO are held in
the low state when EN is low.
TTL compatible threshold with hysteresis. The high side MOSFET
is turned on and the low side MOSFET turned off when IN is high.
All signals are referenced to this ground.
Connect to the gate of the low side N-MOS device with a short, low
inductance path.
