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
of the power MOSFET to limit V
MMBZ5242A (surface mount) 12V Zener diodes are recommended. All
Turn-ON and Turn-OFF tests are performed with a 12V Zener clamp in
series with a small-signal diode connected between V
output to simulate the effects of a 12V protection Zener clamp connected
across the GATE-SOURCE of the power MOSFET.
