Overview
The LM5106SDX/NOPB is a half-bridge gate driver IC designed for synchronous high-side and low-side MOSFET control. 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 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 for driving N-channel MOSFETs
- High-voltage capability supporting bootstrap operation up to 118V
- Non-inverting input logic compatible with standard CMOS levels
Applications
- Synchronous rectification in DC-DC converters
- Half-bridge power stages
- Motor drive applications requiring N-channel MOSFET control
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm RoHS compliance and package variations. The LM5106SDX/NOPB designation indicates a tape-and-reel packaging format. Ensure that the ordering part number matches the exact electrical specifications and thermal requirements of your design before procurement.
Selection Notes
Select this component when designing circuits requiring fast switching speeds for N-channel MOSFETs in half-bridge topologies. The 1.8A sink current capability ensures efficient turn-off performance. Consider the 10-WSON package size for space-constrained PCB layouts. Verify that the input logic voltage levels align with the controller's output capabilities.
Part Context
This device belongs to the LM510x family of gate drivers from Texas Instruments, which includes variants like the LM5104 and LM5105. These components share similar architectural goals but differ in specific drive strengths and timing characteristics. The LM5106 offers a balanced combination of drive current and speed suitable for medium-power applications.
Replacement Considerations
The LM5105SD/NOPB is documented as a direct replacement alternative. Both devices share the same half-bridge configuration and package type. However, verify peak output current specifications and propagation delays to ensure compatibility with existing circuit designs.
