Overview
The LM5100CMY/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments, originally developed under the National Semiconductor brand. It integrates both high-side and low-side drivers in a single package to simplify power stage design. The device supports supply voltages from 9 V to 14 V and delivers a typical output current of 1 A. It features non-inverting logic inputs with a maximum propagation delay of 20 ns. The component operates within an extended temperature range of -40°C to +125°C and is available in an MSOP package.
Feature Summary
- Integrates high-side and low-side gate drivers for half-bridge configurations
- Supports high-voltage operation up to 600 V bus voltage
- Provides robust shoot-through protection via minimum pulse width filtering
- Features independent high and low drive outputs for optimized switching control
Applications
- High-frequency DC-DC converters
- Motor drive systems
- Industrial power supplies
Procurement Notes
Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required MSOP footprint for PCB layout compatibility. Cross-reference the datasheet revision to confirm electrical characteristics align with current design requirements.
Selection Notes
Select this component when a compact solution for driving high-side and low-side MOSFETs or IGBTs is required. It is suitable for applications demanding high-speed switching with minimal external components. Consider the 1 A peak drive current capability against the gate charge requirements of the target power devices. Evaluate the operating temperature range to ensure suitability for industrial environments.
Part Context
This part belongs to the LM5100 family of high-voltage half-bridge gate drivers. It is designed to replace older discrete driver solutions by integrating level shifting and protection features. The device simplifies bill of materials and reduces board space compared to separate high-side and low-side driver ICs.
Replacement Considerations
Check for direct pin-compatible alternatives such as the LM5100BMAX/NOPB or other variants within the LM5100 series. Verify that substitute parts maintain the same voltage rating and drive current specifications.
