Overview
The LM5112SDX/NOPB is a low-side gate driver from Texas Instruments designed for driving N-channel MOSFETs. It features a single channel with inverting and non-inverting inputs, supporting supply voltages between 3.5V and 14V. The device delivers peak output currents of 3A source and 7A sink. Typical propagation delays are 14ns rise and 12ns fall times. It operates within a junction temperature range of -40°C to 125°C and is housed in a compact 6-WSON (3x3) package.
Feature Summary
- Provides high-current drive capability with asymmetric sourcing and sinking performance for efficient MOSFET switching.
- Supports dual input configurations including both inverting and non-inverting logic signals for flexible control integration.
- Operates reliably across an extended industrial temperature range suitable for automotive and harsh environments.
Applications
- Automotive power management systems requiring AEC-Q100 qualified components
- Low-side switching applications for DC-DC converters and motor drivers
- Industrial control circuits utilizing N-channel MOSFET arrays
Procurement Notes
Verify the specific suffix 'SDX' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the 6-WSON package. Cross-reference the Q1 designation for automotive grade requirements. Confirm RoHS compliance status through current datasheets before finalizing procurement orders.
Selection Notes
Select this component when asymmetric drive strength is required, specifically needing higher sink current for faster turn-off times. The wide supply voltage range accommodates various logic levels without external level shifting. Consider the small footprint for space-constrained designs. Verify thermal dissipation capabilities within the WSON package for the intended load conditions.
Part Context
This part belongs to the LM5112 family of low-side gate drivers. It shares functional similarities with other TI drivers like the LM5110 but offers distinct pinout and performance characteristics tailored for specific MOSFET driving needs. The Q1 variant indicates qualification for automotive applications, distinguishing it from standard commercial versions.
Replacement Considerations
Check for direct equivalents such as the LM5112SD/NOPB or LM5112SDDKR depending on packaging preferences. Ensure any substitute maintains the same 6-WSON footprint and electrical parameters. Verify that alternative parts meet the same automotive quality standards if applicable.
