LM5101ASD-1/NOPB

Overview

The LM5101ASD-1/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of sourcing and sinking 3 A peak current. The device operates with a supply voltage range of 9 V to 14 V and supports N-channel MOSFETs up to 118 V. Key electrical parameters include rise and fall times of 10 ns, propagation delay of 26 ns, and turn-on/turn-off delays of 4 ns. It functions within a temperature range of -40°C to +125°C and is housed in an 8-pin WSON package.

Feature Summary

• Provides independent high-side and low-side gate drive signals for half-bridge configurations.
• Delivers high peak output current of 3 A to rapidly charge and discharge MOSFET gates.
• Features fast switching characteristics with 10 ns rise and fall times for efficient operation.
• Includes internal bootstrap diode and UVLO protection for reliable high-voltage driving.

Applications

• High-frequency DC-DC converters
• Synchronous rectification circuits
• Motor control systems
• Industrial power supplies

Procurement Notes

Verify the specific suffix 'SD' against the datasheet to confirm the WSON-8 package variant. Ensure the 'NOPB' designation confirms lead-free status and RoHS compliance as per manufacturer standards. Cross-reference the part number with official Texas Instruments documentation to validate availability and manufacturing status before procurement.

Selection Notes

Select this component when a 3 A drive current is required for high-speed switching applications. It is suitable for designs operating between 9 V and 14 V supply voltages. Consider the 8-pin WSON footprint for space-constrained layouts. Compare against the LM5101B series if lower current (2 A) or different timing specifications are acceptable.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. It complements other variants like the LM5101AMX and LM5101BMAX, which offer similar functionality but may differ in package type, drive current, or timing characteristics. The family is designed for robust performance in demanding power electronics environments.

Replacement Considerations

LM5101ASD/NOPB is a direct equivalent without the NOPB suffix designation. LM5101ASD-1-NOPB shares identical functional specifications and package type. Verify pinout compatibility when substituting with other half-bridge drivers in the same product line.
