MC34151DG

Overview

The MC34151DG is a dual inverting MOSFET gate driver manufactured by onsemi. It features two independent drivers with a peak output current of 1.5 A. The device operates within a supply voltage range of 6.5 V to 18 V and supports CMOS and LSTTL logic inputs. It exhibits rise and fall times of 15 ns each. The component is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel configuration providing independent high-speed control for multiple power switches
• Inverting logic topology ensures precise signal phase alignment for specific bridge topologies
• Robust drive capability delivers 1.5 A peak current to minimize switching losses
• Compatible with standard digital logic families including CMOS and LSTTL

Applications

• High-speed DC motor control systems
• Synchronous rectification circuits
• Power factor correction (PFC) converters
• Isolated gate driving interfaces

Procurement Notes

Verify the exact suffix against official datasheets, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through manufacturer documentation. Ensure the SOIC-8 footprint matches PCB design requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate thermal performance specifications for the intended application environment.

Selection Notes

Select this component when inverting logic is required for dual MOSFET applications. Compare against non-inverting variants like the MC34152DG if signal polarity differs. Evaluate the 1.5 A drive strength against load capacitance requirements. Consider the 0°C to +70°C operating range for environmental constraints. Verify compatibility with available supply voltages between 6.5 V and 18 V.

Part Context

This device belongs to the MC33151 series of high-speed MOSFET gate drivers. It serves as a specialized interface between low-power logic controllers and high-power semiconductor switches. The series emphasizes speed and reliability in industrial power conversion applications. It complements other driver families offering non-inverting or single-channel configurations.

Replacement Considerations

The MC33151DR2G is a reel-packaged variant of the same functional device. The MC34152DG offers identical electrical characteristics but utilizes non-inverting logic. Verify pinout compatibility before substituting with generic dual gate drivers.
