Overview
The LM5101ASD/NOPB is a high-voltage half-bridge gate driver from Texas Instruments designed for driving N-channel MOSFETs. It operates within a supply voltage range of 9 V to 14 V and delivers a peak output current of 3 A. The device features non-inverting logic inputs and supports fast switching with rise and fall times of 10 ns. It is housed in an 8-pin WSON package with an exposed pad, suitable for surface-mount applications across a temperature range of -40°C to +125°C.
Feature Summary
- Integrated high-side and low-side drivers for half-bridge configurations
- Capable of sourcing and sinking 3 A peak output current
- Fast switching performance with 10 ns rise and fall times
- Non-inverting input logic compatibility
Applications
- High-side and low-side N-channel MOSFET gate driving
- Half-bridge power converter topologies
- Industrial motor control systems
- DC-DC converter implementations
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status as indicated in the product documentation. Cross-reference the part number with authorized distributors to validate authenticity and availability. Ensure the procurement channel provides valid traceability records for quality assurance purposes.
Selection Notes
Select this component when a robust half-bridge driver with 3 A output capability is required. The 10 ns transition times suit high-frequency switching applications. Verify that the system supply voltage remains within the 9 V to 14 V operational window. Consider the thermal requirements of the WSON package with exposed pad for effective heat dissipation in dense PCB layouts.
Part Context
This device belongs to the LM5101 family of high-voltage gate drivers. Similar variants include the LM5101AMX/NOPB in SOIC-8 packaging and the LM5101ASD-1/NOPB. These parts share core electrical characteristics but differ in physical footprint and shipping configuration. The family targets applications requiring reliable isolation and drive strength for power switches.
Replacement Considerations
The LM5101ASD-1/NOPB serves as a direct substitute within the same series. Both parts offer identical 3 A drive current and 10 ns switching speeds. Verify package compatibility between WSON-8 variants before implementation. Check datasheet revisions to ensure functional equivalence regarding pinout and electrical limits.
