LM5110-1MX/NOPB

Overview

The LM5110-1MX/NOPB is a dual low-side MOSFET gate driver from Texas Instruments, housed in an SOIC-8 package. It provides independent control for two channels with a peak output current of 5 A per channel. The device operates within a supply voltage range of 3.5 V to 14 V and supports TTL logic inputs. Key timing characteristics include a rise time of 14 ns and a fall time of 12 ns. It functions in an inverting configuration and maintains reliable operation across a temperature range of -40 °C to +125 °C.

Feature Summary

• Dual-channel architecture providing independent low-side drive capabilities
• Negative output voltage capability for enhanced switching performance
• TTL-compatible input logic for direct microcontroller interfacing
• Robust thermal management through SOIC-8 surface mount packaging

Applications

• Synchronous buck converter low-side MOSFET driving
• DC-DC converter bridge leg configurations
• General-purpose power stage control circuits

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per Texas Instruments standards. Confirm the '1M' designation corresponds to the SOIC-8 package variant. Ensure the ordering part number matches the exact datasheet revision required for your design integration. Cross-reference the manufacturer's official documentation for any recent pinout or electrical specification updates before finalizing procurement.

Selection Notes

Select this component when dual independent low-side driving is required with high peak current capability. The negative output voltage feature makes it suitable for applications demanding fast turn-off speeds. Compare against single-channel drivers if only one side requires active control. Consider the SOIC-8 footprint constraints during PCB layout planning. Verify that the 14 ns rise time meets the switching frequency requirements of the target application.

Part Context

This device belongs to the LM5110 series of compound gate drivers designed by Texas Instruments. It serves as a robust interface between low-voltage logic controllers and power MOSFETs. The series emphasizes reliability and speed for industrial and automotive power conversion systems. It complements other Texas Instruments power management solutions by providing precise gate control.

Replacement Considerations

The LM5110-1MX/NOPB may be replaced by the LM5111-2MX/NOPB for similar dual-channel low-side driving needs, though the LM5111 lacks negative output voltage capability. Verify pin compatibility and electrical specifications before substitution.
