MP1909 is a high-frequency, 30V, half bridge, 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. It is available in an 8-pin SOT-583 (1.6mmx2.1mm) package. Applications include electronic cigarettes, wireless charging, drones, avionics DC/DC converters and active-clamp forward converters.
