Locally decouple to V
close to IC as possible.
The HI input is compatible with TTL input thresholds. Unused HI
input should be tied to ground and not left open.
The LI input is compatible with TTL input thresholds. Unused LI input
should be tied to ground and not left open.
All signals are referenced to this ground.
Connect to the gate of the low-side N-MOS device.
Connect to the negative terminal of the bootstrap capacitor and to
the source of the high-side N-MOS device.
Connect to the gate of the high-side N-MOS device.
Connect the positive terminal of the bootstrap capacitor to HB and
the negative terminal of the bootstrap capacitor to HS. The bootstrap
capacitor should be placed as close to IC as possible.
