temperature range.

Note 1: Quiescent current OFF is for both channels in OFF condition.

Note 2: Quiescent current ON is per driver and is measured independently.

The gate voltage is clamped to 12V above the rail to simulate the effects of

protection clamps connected across the GATE-SOURCE of the power

MOSFET.

Note 3: Zener diode clamps must be connected across the GATE-SOURCE

MMBZ5242A (surface mount) 12V Zener diodes are recommended. All

Turn-ON and Turn-OFF tests are performed with a 12V Zener clamp in

output to simulate the effects of a 12V protection Zener clamp connected

across the GATE-SOURCE of the power MOSFET.
