Application Information

SOIC-8 LLP-10

V_DD

Positive gate drive supply Locally decouple to V_SSusing low ESR/ESL capacitor, located as close to

IC as possible.

High side gate driver

bootstrap rail

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.

High side gate driver output Connect to gate of high side MOSFET with short low inductance path.

High side MOSFET source Connect to bootstrap capacitor negative terminal and source of high side

connection

MOSFET.

Deadtime programming pin Resistor from RT to ground programs the deadtime between high and low

side transitions.The resistor should be located close to the IC to minimize

noise coupling from adjacent traces.

Control input

Logic 1 equals High Side ON and Low Side OFF. Logic 0 equals High Side

OFF and Low Side ON.

V_SS

Ground return

All signals are referenced to this ground.

Low side gate driver output Connect to the gate of the low side MOSFET with a short low inductance

path.

Note: For LLP-10 package, it is recommended that the exposed pad on the bottom of the SM74104 be soldered to ground plane on the PC board, and

the ground plane should extend out from beneath the IC to help dissipate the heat. Pins 5 and 6 have no connection.
