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.
