MP1906
80V, Half-Bridge, Gate Driver
The Future of Analog IC Technology
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.
