Overview
The LM5106SDX/NOPB is a half-bridge gate driver IC designed for synchronous MOSFET applications. It features non-inverting inputs and supports N-channel MOSFETs with peak output currents of 1.2A source and 1.8A sink. The device operates within an 8V to 14V supply range and withstands high-side bootstrap voltages up to 118V. Typical rise and fall times are 15ns and 10ns, respectively. Logic thresholds are defined at 0.8V (VIL) and 2.2V (VIH). It is housed in a 10-WSON package and functions across a junction temperature range of -40°C to 125°C.
Feature Summary
- Synchronous half-bridge configuration optimized for driving external N-channel power MOSFETs.
- High-voltage capability supporting bootstrap operation up to 118V for high-side switching.
- Non-inverting input logic compatible with standard control interfaces.
Applications
- Synchronous buck converter topologies
- Half-bridge power stages
- Motor drive circuits
Procurement Notes
Verify the specific suffix NOPB confirms RoHS compliance and lead-free manufacturing status as per Texas Instruments documentation. Confirm the 10-WSON package dimensions match the design footprint requirements. Ensure the operating voltage range aligns with the system's power supply rails before finalizing procurement specifications.
Selection Notes
Select this component when a compact half-bridge driver is required for high-side N-channel MOSFETs. The 118V bootstrap rating accommodates wide input voltage ranges. Verify that the 1.8A sink current meets the gate charge requirements of the target power switches. Consider the 10-WSON package size constraints during PCB layout planning.
Part Context
This part belongs to the LM510x family of gate drivers from Texas Instruments. It serves as a successor or alternative to earlier variants like the LM5105, offering updated manufacturing standards. The device integrates essential protection features while maintaining a small form factor suitable for dense power electronics designs.
Replacement Considerations
Direct substitutes include other LM5106 variants with different packaging options. Cross-reference pinouts and electrical characteristics carefully when replacing legacy parts like the LM5105 to ensure compatibility with existing circuit designs.
