LM5114BMF/NOPB

Overview

The LM5114BMF/NOPB is a single low-side MOSFET gate driver manufactured by Texas Instruments. It features a peak output current of 7.6 A and operates within a supply voltage range of 4 V to 12.6 V. The device utilizes an SOT-23-6 surface-mount package. Electrical characteristics include a rise time of 3.2 ns and a fall time of 8 ns. Logic input compatibility includes TTL levels. The operational temperature range spans from -40 °C to +125 °C, with maximum on and off delay times specified at 25 ns.

Feature Summary

• Capable of delivering high peak source and sink currents for rapid switching
• Features controllable rise and fall times to manage electromagnetic interference
• Supports direct interface with standard logic families including TTL

Applications

• Low-side switching in synchronous buck converters
• Gate driving for power MOSFETs in isolated DC-DC topologies
• High-speed switching applications requiring precise timing control

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official documentation to ensure compliance with required electrical specifications and environmental standards. Confirm that the ordering part number matches the exact package variant and temperature grade intended for the design. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for driving low-side power switches is required. The small SOT-23-6 footprint makes it suitable for space-constrained designs. Ensure the application voltage does not exceed the 12.6 V maximum limit. Consider the 7.6 A peak current capability relative to the target MOSFET gate charge requirements to achieve desired switching speeds without excessive thermal stress.

Part Context

This device belongs to the LM5114 series of gate drivers designed for high-performance power management applications. It serves as a critical interface between control logic and power stages. The NOPB suffix indicates lead-free construction compliant with RoHS directives. Related development tools such as the LM5114BSDEVAL/NOPB are available for circuit validation and performance testing.

Replacement Considerations

Direct substitutes within the same family include variants like LM5114BMFX/NOPB, which share identical electrical characteristics but differ in packaging format. Verify pinout compatibility and thermal performance when considering alternative packages or suffixes from the manufacturer's portfolio.
