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.

FEATURES

 Drives an N-Channel MOSFET Half-Bridge

 115V Bootstrap Voltage Range

 On-Chip Bootstrap Diode

 Typical Propagation Delay of 20ns

 Gate Driver Matching of Less than 5ns

 Drives a 2.2nF Load with 15ns of Rise Time

and 10ns of Fall Time at 12V VDD

 TTL-Compatible Input

 Quiescent Current of Less than 150µA

 UVLO for Both High-Side and Low-Side

Gate Drivers

 Available in a QFN-8 (4mmx4mm) Package

APPLICATIONS

 Motor Drivers

 Telecom Half-Bridge Power Supplies

 Avionics DC/DC Converters

 Two-Switch Forward Converters

 Active Clamp Forward Converters
