MC34152P.pdf

The MC34152/MC33152 are dual noninverting high speed drivers
specifically designed for applications that require low current digital
signals to drive large capacitive loads with high slew rates. These
devices feature low input current making them CMOS/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 system erratic
operation at low supply voltages.
Typical applications include switching power supplies, dc−to−dc
converters, capacitor charge pump voltage doublers/inverters, and
motor controllers.
This device is available in dual−in−line and surface mount packages.
