LM5101CSD

Overview

The LM5101CSD/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers in a compact 10-pin LLP package. The device supports N-channel MOSFETs with a supply voltage range of 9 V to 14 V. It delivers a peak output current of 1 A per channel. Key electrical characteristics include a maximum propagation delay of 26 ns, rise time of 990 ns, and fall time of 715 ns. The operating junction temperature range spans from -40°C to +125°C.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge configurations
• Supports non-inverting logic input control for straightforward interface compatibility
• Designed for driving N-channel power MOSFETs with robust output capability

Applications

• Synchronous rectification in DC-DC converters
• Motor drive circuits requiring half-bridge topology
• Isolated power supply gate driving applications

Procurement Notes

Verify the complete part number includes the NOPB suffix for lead-free compliance when ordering. Confirm the LLP-10 package variant matches the design footprint requirements. Cross-reference the specific revision level against the latest datasheet to ensure pinout consistency. Validate that the supplier provides original manufacturer documentation for quality assurance purposes.

Selection Notes

Select this component when a compact solution is required for half-bridge applications due to its small LLP package. Choose over larger packages if board space is constrained but moderate 1 A drive current suffices. Consider the 9 V to 14 V supply range limitations compared to wider voltage variants. Ensure the thermal performance of the LLP package meets the system's heat dissipation needs under continuous operation.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. The family includes variants like LM5101AMX and LM5101BMAX which offer higher current capabilities or different packaging options. The LM5101CSD specifically targets cost-sensitive applications requiring a balance between performance and size in the LLP-10 form factor.

Replacement Considerations

LM5101ASD/NOPB offers higher 3 A drive current in the same package. LM5101BSD/NOPB provides intermediate 2 A drive capability. Verify pin compatibility and electrical specifications before substituting these alternatives.
