MC33152D

Overview

The MC33152D is a high-speed dual MOSFET driver manufactured by onsemi, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 6.1V to 18V and delivers a peak output current of 1.5A. The device features Schmitt trigger inputs for noise immunity and provides true output polarity. Key timing parameters include a propagation delay of 40ns, with rise and fall times of 36ns and 32ns respectively. It supports IGBT and N-channel MOSFET switching applications.

Feature Summary

• Dual channel configuration for independent control of two power switches
• Schmitt trigger input circuitry ensures clean signal transitions and noise rejection
• Totem-pole output stage design enables rapid charging and discharging of gate capacitance
• True logic compatibility allows direct interfacing with standard digital logic families

Applications

• High-frequency DC-DC converter topologies
• Motor drive bridge circuits
• Inverter systems requiring fast switching transitions

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-8 surface mount package variant rather than the PDIP through-hole version. Confirm RoHS compliance status as historical data indicates potential non-compliance for older production runs. Ensure the supplier source provides official datasheets matching the ON Semiconductor revision history to validate electrical characteristics.

Selection Notes

Select this component when dual isolated or common-ground high-side/low-side driving is required in compact designs. The SOIC-8 package offers thermal performance suitable for moderate power dissipation. Consider the 1.5A peak current capability against the target MOSFET's total gate charge requirements to ensure adequate switching speed without excessive heat generation in the driver IC.

Part Context

This part belongs to the MC3315x series of high-speed drivers from onsemi. It serves as a successor to earlier Motorola designs, maintaining functional compatibility while offering improved packaging options. The series is widely used in industrial power conversion where reliable switching performance under varying load conditions is critical for system efficiency.

Replacement Considerations

Direct pin-compatible alternatives may include the MC34152D for similar specifications. Cross-reference with Texas Instruments TPS2811 for comparable dual driver functionality. Verify that any substitute maintains the same 1.5A output current rating and 6.1V minimum operating voltage to ensure circuit stability.
