LM5107MAX/NOPB

Overview

The LM5107MAX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for high-side and low-side MOSFET control. It operates within a supply voltage range of 8 V to 14 V and delivers a peak output current of 1.4 A. The device features independent drivers with TTL-compatible logic inputs. It supports fast switching with rise and fall times of 15 ns and a maximum propagation delay of 56 ns. The component is housed in an SOIC-8 package and functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides independent high-side and low-side gate drive capabilities for half-bridge configurations
• Features fast switching performance with 15 ns rise and fall times
• Supports TTL-compatible logic input signals for direct interface with digital controllers

Applications

• High-side and low-side MOSFET gate driving in power conversion circuits
• Industrial motor control systems requiring robust half-bridge drivers
• DC-DC converter topologies utilizing external N-channel MOSFETs

Procurement Notes

Verify the specific suffix 'MAX' confirms the tape-and-reel packaging format rather than tube packaging. Confirm the '/NOPB' designation indicates lead-free and RoHS compliance status as per the manufacturer's latest documentation. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.

Selection Notes

Select this component when a single-chip solution for independent high-side and low-side driving is required. It is suitable for applications needing moderate peak current capability up to 1.4 A. Consider the SOIC-8 package size constraints and the 8 V to 14 V supply voltage range during circuit design. Verify that the 56 ns propagation delay meets the timing requirements of the specific application.

Part Context

This device belongs to the LM5107 series of half-bridge gate drivers from Texas Instruments. It is functionally similar to other variants like the LM5107MA but differs in packaging configuration. The series is designed for driving external N-channel MOSFETs in various power management and motor control applications.

Replacement Considerations

Publicly confirmed substitute part numbers include LM5107MA and LM5107MAX. Verify compatibility regarding packaging type and electrical specifications before substitution.
