DESCRIPTION

The MP1925 is a high-frequency, half-bridge,

N-channel power MOSFET driver. Its low-side

and high-side driver channels are controlled

independently and matched with less than 5ns

of time delay. Under-voltage lockout (UVLO) on

both the high-side and low-side supplies forces

the outputs low in the event that the supply is

insufficient. The integrated bootstrap diode

reduces the external component count.

The MP1925 is available in a QFN-8

4mmx4mm) package.
