LM5102MMX/NOPB

Overview

The LM5102MMX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for driving high-side and low-side MOSFETs in power conversion applications. It operates within a supply voltage range of 9 V to 14 V and supports peak output currents of 1.6 A for both sourcing and sinking. The device features non-inverting logic inputs with defined threshold levels of 0.8 V and 2.2 V. It is housed in a 10-VSSOP surface-mount package and ensures reliable performance across an extended junction temperature range from -40°C to +125°C.

Feature Summary

• Provides robust 1.6 A peak drive current capability for efficient switching of external power MOSFETs.
• Features independent channel configuration suitable for half-bridge topologies with non-inverting input logic.
• Includes internal bootstrap support enabling high-side operation up to 118 V.

Applications

• High-frequency DC-DC converter designs
• Motor control systems requiring isolated gate driving
• Industrial power supply inverters

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure that the ordering information matches the exact part number variant required for your production line, as suffixes can indicate differences in packaging or testing criteria.

Selection Notes

Select this component when a compact half-bridge solution with moderate drive strength is required. The 10-VSSOP package offers space efficiency for dense layouts. Consider the 1.6 A output current limit and the 118 V high-side voltage capability to ensure compatibility with the target power stage requirements.
