MC34151, MC33151

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.

• T wo Independent Channels with 1.5 A Totem Pole Output

• Output Rise and Fall Times of 15 ns with 1000 pF Load

• CMOS/LSTTL Compatible Inputs with Hysteresis

• Undervoltage Lockout with Hysteresis

• Low Standby Current

• Efficient High Frequency Operation

• Enhanced System Performance with Common Switching Regulator

Control ICs

• Pin Out Equivalent to DS0026 and MMH0026
