LM5114ASD/NOPB

Overview

The LM5114ASD/NOPB is a single low-side MOSFET gate driver from Texas Instruments, housed in a WSON-6 surface-mount package. It delivers a peak output current of 7.6 A with a supply voltage range of 4 V to 12.6 V. The device features controllable rise and fall times, specified at 3.2 ns and 8 ns respectively, alongside maximum on/off delay times of 12 ns. Operating temperatures span from -40°C to +125°C, with a typical quiescent current of 950 µA.

Feature Summary

Provides high peak drive current for efficient MOSFET switching
Features externally controllable rise and fall times for EMI optimization
Supports TTL logic input levels for direct microcontroller interfacing

Applications

Low-side switching in DC-DC converters
Motor control applications requiring single-ended drive
General-purpose power management circuits

Procurement Notes

Verify the specific suffix 'ASD' corresponds to the WSON-6 package and tape-and-reel configuration when sourcing. Confirm that the NOPB designation indicates RoHS compliance and lead-free construction. Cross-reference the manufacturer datasheet to ensure the component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for designs requiring a single low-side driver with adjustable switching speeds. The WSON-6 package offers a compact footprint suitable for space-constrained PCB layouts. Ensure the driving circuit can support the 7.6 A peak current capability without excessive voltage drop or thermal issues in the trace routing.

Part Context

This part belongs to the LM5114 series of gate drivers, which are designed for robust performance in power conversion systems. The LM5114 family includes variants with different packages such as SOT-23-6, providing flexibility for various board space requirements while maintaining consistent electrical characteristics across the series.
