MC34151PG

Overview

The MC34151PG is a dual inverting high-speed MOSFET gate driver manufactured by onsemi, housed in an 8-pin PDIP package. It provides two independent channels with 1.5 A totem pole outputs, designed to drive large capacitive loads with high slew rates. The device features low input current for CMOS and LSTTL logic compatibility, input hysteresis for fast switching, and undervoltage lockout with hysteresis to prevent erratic operation at low supply voltages. Operating temperatures range from 0°C to 70°C.

Feature Summary

• Dual independent channels with 1.5 A totem pole output capability
• CMOS and LSTTL compatible inputs with integrated hysteresis
• Undervoltage lockout mechanism prevents erratic system operation
• High-frequency efficient operation suitable for switching applications

Applications

• Switching power supplies
• DC to DC converters
• Capacitor charge pump voltage doublers/inverters
• Motor controllers

Procurement Notes

Verify the specific suffix 'PG' corresponds to the PDIP (Plastic Dual In-line Package) configuration when sourcing. Confirm that the manufacturer is onsemi, as part numbers may be shared or rebranded. Ensure the operating temperature range of 0°C to 70°C meets the environmental requirements of the target application. Cross-reference the datasheet revision to ensure compatibility with existing design specifications.

Selection Notes

Select this component when driving large capacitive loads requires high slew rates and low input current consumption. It is suitable for systems needing CMOS or LSTTL logic interface compatibility. The built-in undervoltage lockout makes it ideal for applications requiring protection against low supply voltage conditions. Consider the PDIP package for through-hole mounting requirements.

Part Context

The MC34151 series includes variants such as the MC34151D and MC34151DG, which share similar electrical characteristics but differ in packaging. The MC34151PG specifically denotes the through-hole PDIP version, while other suffixes indicate surface-mount options like SOIC. This family is designed for high-speed switching applications where efficiency and performance are critical.

Replacement Considerations

Check for pin-out equivalence with DS0026 and MMH0026 devices. Verify that any substitute maintains the 1.5 A output current capability and 15 ns rise/fall times. Ensure the replacement supports the same logic input compatibility and undervoltage lockout thresholds.
