LM5101ASDX-1/NOPB

Overview

The LM5101ASDX-1/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It provides independent high-side and low-side outputs with a peak output current of 3 A. The device operates within a supply voltage range of 7.5 V to 14 V and supports TTL logic inputs. It features fast switching characteristics, including rise and fall times of 10 ns. The component is housed in an 8-pin WSON package with an exposed pad for thermal management. It is designed for operation across a temperature range from -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side gate drive capabilities for half-bridge configurations
• Delivers high peak output current capability for efficient MOSFET switching
• Features fast propagation delays and switching times for high-frequency applications
• Includes built-in protection mechanisms such as under-voltage lockout

Applications

• High-voltage motor control systems
• Industrial power conversion circuits
• Inverter topologies requiring isolated or floating gate drives

Procurement Notes

Verify the specific suffix 'X' against the official Texas Instruments datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout. Cross-reference the RoHS status and environmental compliance details directly with the manufacturer's certification documents before finalizing procurement orders.

Selection Notes

Select this component when a 3 A peak drive current is required for high-voltage half-bridge applications. Consider the 8-pin WSON package size constraints and thermal dissipation needs due to the exposed pad design. Evaluate the 7.5 V minimum supply voltage requirement against your system's available power rails. Confirm compatibility with TTL logic levels for input signal interfacing.

Part Context

This device belongs to the LM5101A series of gate drivers from Texas Instruments. The series offers various packages and current ratings to suit different power density requirements. The LM5101ASDX-1/NOPB specifically utilizes the WSON form factor, distinguishing it from SOIC variants like the LM5101AMX-NOPB which may have different thermal and pin-out characteristics despite similar electrical functions.

Replacement Considerations

LM5101ASD-1/NOPB: Verify package equivalence and lead availability. LM5101ASD-1-NOPB: Check for identical pinout and electrical parameters. Ensure any substitute maintains the 3 A output current and 100 V rating.
