MC33151DR2

Overview

The MC33151DR2 is a dual inverting MOSFET gate driver manufactured by onsemi. It features two drivers with a peak output current of 1.5 A and operates within a supply voltage range of 6.5 V to 18 V. The device utilizes an SOIC-8 surface-mount package and supports CMOS and TTL logic inputs. Key timing parameters include a propagation delay of 100 ns, rise time of 15 ns, and fall time of 15 ns. It functions reliably across an operating temperature range of 0 °C to +70 °C.

Feature Summary

• Dual-channel configuration providing independent control for high-side or low-side switching applications
• Inverting logic design compatible with standard digital control signals
• High-speed switching capability with symmetric rise and fall times for efficient power management

Applications

• DC-DC converter synchronous rectification
• Motor drive bridge circuits
• Power supply gate control

Procurement Notes

Verify the specific suffix DR2 against official datasheets to confirm the SOIC-8 package and tape-and-reel packaging format. Ensure the component meets the required industrial temperature range of 0 °C to +70 °C for your specific application environment. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a dual inverting gate driver is required for medium-power MOSFETs. It is suitable for designs needing 1.5 A drive strength with minimal propagation delay. Consider the SOIC-8 footprint constraints and the specific inverting logic requirement compared to non-inverting alternatives like the MC33152 series.

Part Context

This device belongs to the MC3315x family of high-speed MOSFET gate drivers from onsemi. It shares functional similarities with the MC34151 but differs in package type and specified operating temperature range. The family is designed for general-purpose power switching applications requiring reliable isolation between control logic and power stages.

Replacement Considerations

MC34151DR2G: Pin-compatible alternative with extended temperature range (-40 °C to +85 °C). MC33152DR2G: Non-inverting version; requires logic inversion if used as a direct substitute.
