LM27222M/NOPB

Overview

The LM27222M/NOPB is a half-bridge gate driver IC manufactured by Texas Instruments. It features a non-inverting input configuration and supports synchronous MOSFETs. The device operates within a supply voltage range of 4V to 6.85V. Peak output current capabilities are specified at 3A for sourcing and 4.5A for sinking. High-side voltage withstands up to 33V via bootstrap. Typical rise and fall times are 17ns and 12ns respectively. It functions across an operating temperature range of -40°C to 125°C TJ. The component is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides high-speed switching performance with low propagation delays for efficient power stage control
• Supports synchronous N-channel MOSFET configurations with robust peak drive currents
• Operates reliably across extended industrial temperature ranges

Applications

• Synchronous buck converter designs
• Half-bridge power stage driving
• DC-DC converter applications requiring fast switching

Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm the SOIC-8 package variant, as datasheets often list the SD (WSON) version primarily. Confirm RoHS compliance status and check for any Product Change Notices or End-of-Life announcements from Texas Instruments prior to finalizing procurement plans.

Selection Notes

Select this component when a half-bridge topology with non-inverting logic is required. Ensure the application voltage does not exceed the 6.85V supply limit. Verify that the PCB layout accommodates the 8-SOIC footprint and thermal requirements for the specified peak currents.

Part Context

This part belongs to the LM2722x family of high-speed gate drivers. It complements other variants like the LM27222SD/NOPB which utilizes an 8-WSON package. The family focuses on providing reliable gate drive signals for power management integrated circuits in compact form factors.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family such as the LM27222SD/NOPB if package changes are acceptable. Verify electrical parameters match exactly before substituting.
