MC34151 Datasheet, PDF (1/10 Pages) ON Semiconductor – High Speed Dual MOSFET Drivers

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.
• Two Independent Channels with 1.5 A Totem Pole Output
