MC34151P

Overview

The MC34151P is a dual inverting high-speed MOSFET gate driver manufactured by onsemi. It operates within a supply voltage range of 6.5 V to 18 V and delivers a peak output current of 1.5 A through two independent totem-pole channels. The device features rise and fall times of 32 ns and 31 ns respectively, with a propagation delay of 100 ns. Designed for surface-mount or through-hole integration, it utilizes an 8-pin PDIP package. The operational temperature range spans from -40 °C to +85 °C, supporting efficient high-frequency switching applications.

Feature Summary

• Dual independent channels providing high-current totem-pole outputs for driving large capacitive loads
• CMOS and LSTTL logic compatible inputs with hysteresis for fast output switching
• Integrated undervoltage lockout with hysteresis to prevent erratic operation at low supply voltages

Applications

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

Procurement Notes

Verify the specific suffix 'P' indicates the PDIP through-hole package variant rather than SOIC surface-mount versions. Confirm the manufacturer is onsemi (formerly ON Semiconductor) and check for RoHS compliance status as indicated in technical documentation. Ensure the ordering information matches the exact pin count and thermal specifications required for the target PCB layout.

Selection Notes

Select this component when dual-channel inversion is required for driving N-channel MOSFETs in bridge configurations. The 1.5 A output capability suits moderate-power applications, while the 6.5 V minimum supply allows compatibility with standard logic levels. Consider the PDIP package constraints if automated surface-mount assembly is not available or if higher mechanical robustness is needed for prototyping.

Part Context

This part belongs to the MC34151/MC33151 family of high-speed dual MOSFET drivers. It serves as a direct replacement for legacy devices like DS0026 and MMH0026. The series is designed to enhance system performance when paired with common switching regulator control ICs, offering low standby current and efficient high-frequency operation capabilities.

Replacement Considerations

Direct pin-out equivalents include DS0026 and MMH0026. For non-inverting functionality, consider the MC34152 series. Verify package compatibility when substituting with MC33151 variants, as electrical characteristics remain consistent across the family.
