High Speed Dual

MOSFET Drivers

The MC34151/MC33151 are dual inverting high speed drivers

specifically designed for applications that require low current digital

circuitry to drive large capacitive loads with high slew rates. These

devices feature low input current making them CMOS and LSTTL

logic compatible, input hysteresis for fast output switching that is

independent of input transition time, and two high current totem pole

outputs ideally suited for driving power MOSFETs. Also included is

an undervoltage lockout with hysteresis to prevent erratic system

operation at low supply voltages.

Typical applications include switching power supplies, dc to dc

converters, capacitor charge pump voltage doublers/inverters, and

motor controllers.

These devices are available in dual−in−line and surface mount

packages.
