DESCRIPTION

The MP1906 is a high-performance, 80V, gate

driver that can drive two external N-MOSFETs

in a half-bridge configuration with a 12V gate

supply. It accepts independent gate input

signals and provides shoot-through prevention.

During under-voltage lockout, the output of the

high- and low-side drivers goes low to prevent

erratic operation under low supply conditions.

The high-current driving capability and short dead

time make it suitable for high-power and high-

efficiency power applications, such as telecom

DC-DC converters. The compact 8-pin SOIC

package minimizes the component count and

the board space.
