Overview
The LM5101ASDX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for high-voltage applications up to 100 V. It features an independent configuration with two N-channel MOSFET drivers and operates within a supply voltage range of 7.5 V to 14 V. The device delivers a peak output current of 3 A with fast switching characteristics, including rise and fall times of 10 ns. It supports TTL logic inputs and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-pin WSON format, it integrates essential protections such as under-voltage lockout.
Feature Summary
- Provides independent high-side and low-side gate drive capabilities for N-channel MOSFETs
- Supports high-voltage operation up to 100 V with integrated bootstrap diode
- Features fast switching performance with 10 ns rise and fall times
- Includes under-voltage lockout protection for reliable system operation
Applications
- High-voltage motor control systems
- Industrial power conversion circuits
- Isolated DC-DC converter designs
Procurement Notes
Verify the exact suffix 'DX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the WSON-8 package. Confirm RoHS compliance status through the latest TI documentation before finalizing procurement orders.
Selection Notes
Select this component when a robust half-bridge driver is required for high-voltage environments. The 3 A output current capability suits medium-power MOSFETs. Consider the WSON package size for space-constrained designs. Verify that the 7.5 V minimum supply voltage aligns with your system's available rail.
Part Context
This part belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. The family offers various speed and current variants to suit different power levels. The LM5101 series is widely used in industrial and automotive applications requiring reliable high-side and low-side switching with integrated protection features.
Replacement Considerations
Check for LM5101AMX/NOPB or LM5101BMAX/NOPB if different current ratings or packages are acceptable. Verify pin-to-pin compatibility and electrical parameters before substitution.
