Overview
The LM5101BMAX is a half-bridge gate driver manufactured by Texas Instruments, designed for driving high-side and low-side N-channel MOSFETs. It operates within a supply voltage range of 9 V to 14 V and delivers a peak output current of 2 A. The device features independent high-side and low-side drivers with TTL-compatible logic inputs. Key timing parameters include a maximum propagation delay of 26 ns, with rise and fall times of 570 ns and 430 ns, respectively. It supports an operating temperature range from -40°C to +125°C and is housed in an 8-pin SOIC package.
Feature Summary
- Provides independent high-side and low-side gate drive outputs for N-channel MOSFET control
- Features TTL-compatible logic inputs for direct interface with standard digital controllers
- Supports wide operating temperature range suitable for industrial and automotive environments
Applications
- Half-bridge power stage configurations
- High-side and low-side N-channel MOSFET switching applications

Procurement Notes
Verify the exact part number suffix against official Texas Instruments documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and lead times through authorized distributors. Cross-reference datasheet revisions to ensure compatibility with current design requirements.
Selection Notes
Select this component when a 2 A peak drive current is sufficient for the target MOSFET capacitance. Consider the 26 ns propagation delay for timing-sensitive applications. Ensure the input logic levels match the TTL specification. Evaluate thermal performance within the specified -40°C to +125°C junction temperature range.
Part Context
The LM5101BMAX belongs to the LM5101B series of half-bridge gate drivers. It shares functional similarities with other variants like the LM5101AM and LM5101CMA but differs in drive strength and switching speed characteristics. This specific variant offers a balanced performance profile for general-purpose half-bridge applications requiring moderate drive capability.
Replacement Considerations
