Overview
The LM25101CMA/NOPB is a half-bridge gate driver manufactured by Texas Instruments, formerly National Semiconductor. It features two independent drivers with peak output currents of 3A and 2A for high-side and low-side MOSFET control. The device operates within a supply voltage range of 9V to 18V and supports bootstrap voltages up to 80V. It utilizes an SOIC-8 package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Provides independent high-side and low-side gate drive capabilities for half-bridge configurations.
- Supports high-voltage operation with integrated bootstrap functionality for floating high-side driving.
- Features fast switching characteristics with short rise and fall times to minimize conduction losses.
Applications
- High-voltage DC-DC converter topologies
- Half-bridge power stage implementations
- Industrial motor drive systems
Procurement Notes
Verify the manufacturer origin as Texas Instruments acquired National Semiconductor. Confirm the specific suffix 'C' indicates the correct performance grade. Ensure the SOIC-8 package matches the design footprint. Check RoHS compliance status for environmental regulations. Validate the operating temperature range against system requirements.
Selection Notes
Select this component when a robust half-bridge driver is required for high-voltage applications. The 3A and 2A output currents accommodate various MOSFET gate charges. The wide supply voltage range ensures compatibility with standard logic levels. Consider the thermal performance in the SOIC-8 package for heat dissipation needs.
Part Context
This part belongs to the LM25101 family of high-voltage half-bridge gate drivers. It succeeds earlier National Semiconductor designs under the Texas Instruments portfolio. The device integrates essential protection features for reliable power switching. It serves as a direct replacement for legacy components in established industrial designs.
Replacement Considerations
LM25101AM/NOPB offers similar specifications with potential variations in electrical parameters. LM25101BM/NOPB provides alternative performance grades within the same family. Verify pinout compatibility before substituting with these variants. Ensure voltage ratings match the application's maximum operating conditions.
