Order this document by MC34151/D 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 MC34151 MC33151 HIGH SPEED DUAL MOSFET DRIVERS SEMICONDUCTOR TECHNICAL DATA P SUFFIX PLASTIC PACKAGE CASE 626 8 1 • • • • • • • 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 8 1 D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) PIN CONNECTIONS N.C. 1 2 3 4 (Top View) 8 7 6 5 N.C.
