MC33151PG

Overview

The MC33151PG is a dual inverting high-speed MOSFET gate driver manufactured by onsemi. It features two independent channels with 1.5 A peak source and sink currents, designed to drive large capacitive loads with high slew rates. The device operates within a supply voltage range of 6.5 V to 18 V and supports CMOS and LSTTL logic inputs with hysteresis. Key electrical parameters include rise and fall times of approximately 31 ns and 32 ns, respectively, with a propagation delay of 100 ns. It is housed in an 8-pin PDIP package for through-hole mounting.

Feature Summary

• Dual independent channels providing high-current totem pole outputs for efficient power MOSFET switching
• Integrated undervoltage lockout with hysteresis to prevent erratic operation at low supply voltages
• CMOS and LSTTL logic compatible inputs featuring hysteresis for fast output switching independent of input transition time

Applications

• Switching power supplies
• DC to DC converters
• Motor controllers

Procurement Notes

Verify the specific suffix 'PG' confirms the PDIP-8 through-hole package variant when ordering. Confirm the manufacturer is onsemi, as generic listings may not distinguish between original and alternative sources. Ensure the component meets the required operating temperature range of -40°C to 85°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when driving large capacitive loads requiring high slew rates from low-current digital circuits. It is suitable for applications needing CMOS or LSTTL compatibility. Consider the 1.5 A output current capability and the 6.5 V to 18 V supply range. The dual-channel configuration allows for simultaneous control of multiple MOSFETs in bridge or half-bridge topologies.

Part Context

The MC33151 series belongs to onsemi's family of high-speed dual MOSFET drivers. It serves as a pin-out equivalent to legacy devices like DS0026 and MMH0026. The PG suffix specifically denotes the plastic dual in-line package version, distinguishing it from surface-mount variants such as the DG (SOIC-8) or D (SOIC-8) versions within the same functional family.

Replacement Considerations

Direct pin-compatible substitutes include the MC34151DG for surface mount applications. Verify that any replacement maintains the 1.5 A output current and 18 V maximum supply voltage specifications. Ensure the substitute also offers CMOS/LSTTL compatibility and similar propagation delays for circuit integrity.
