MC34152DG

Overview

The MC34152DG is a high-speed dual non-inverting MOSFET gate driver manufactured by onsemi. It operates within a supply voltage range of 6.1 V to 18 V and delivers a peak output current of 1.5 A. The device features symmetric rise and fall times of 15 ns, ensuring precise switching control. It is housed in an SOIC-8 surface-mount package and supports CMOS and LSTTL logic inputs. The component functions reliably across an operating temperature range from -40°C to +85°C with a maximum power dissipation of 560 mW.

Feature Summary

• Dual-channel architecture providing independent non-inverting drive signals for synchronous or half-bridge configurations.
• High-speed switching capability with 15 ns rise and fall times for efficient power stage control.
• Robust input compatibility with standard CMOS and LSTTL logic families for flexible interfacing.

Applications

• Synchronous buck converter topologies requiring isolated or non-isolated gate drive.
• Half-bridge and full-bridge power conversion circuits.
• General-purpose MOSFET switching applications in industrial power supplies.

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements. Validate the operating temperature range specifications against your environmental design constraints before finalizing orders.

Selection Notes

Select this component when non-inverting logic behavior is required for the gate drive application. Consider the 1.5 A output current capability for driving medium-power MOSFETs efficiently. Evaluate the 15 ns propagation delay against your system's switching frequency requirements. Compare the SOIC-8 thermal performance against alternative packages if higher power dissipation is anticipated in dense layouts.

Part Context

This part belongs to the MC33152 series of high-speed dual MOSFET drivers. It serves as the non-inverting counterpart to the MC34151, which offers inverting functionality. Both devices share similar electrical characteristics and packaging, allowing for design flexibility based on logic signal polarity requirements in power management systems.

Replacement Considerations

The MC34152DR2G is a tape-and-reel variant of the same functional device. Verify that the reel quantity meets production needs without altering electrical performance. Cross-reference with other MC33152 family members only if logic inversion differences are acceptable.
