DESCRIPTION

The MP1909 is a high-frequency, 30V, halfbridge,

N-channel power MOSFET driver. Its

low-side and high-side driver channels are

controlled by a signal input. Internal adaptive

dead time control circuitry reduces the switching

power loss and prevents shoot-through.

Both outputs are disabled when the EN pin is

pulled low. The integrated bootstrap diode

reduces external component count. Undervoltage

lockout (UVLO) functionality protects the

IC from operating at insufficient power supplies.

Thermal shutdown protection functions can

protect the IC from over-temperature conditions.
