LM5101BMAX/NOPB

Overview

The LM5101BMAX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of sourcing and sinking 2 A peak currents. The device operates within a supply voltage range of 9 V to 14 V and supports TTL logic inputs. Key electrical parameters include a maximum propagation delay of 26 ns, with rise and fall times of 570 ns and 430 ns respectively. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side gate drive capabilities for half-bridge configurations.
• Supports direct interface with standard TTL logic input signals.
• Delivers robust 2 A output current capability for driving power MOSFETs.

Applications

• High-voltage power conversion systems
• Industrial motor control applications
• Inverter circuits requiring isolated switching

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS standards as per manufacturer specifications. Confirm the package type matches the required SOIC-8 footprint for PCB layout compatibility. Ensure the operating voltage requirements align with the 9 V to 14 V supply range defined in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dedicated half-bridge driver with moderate current drive is required. The 2 A output current suits standard medium-power MOSFETs. Consider the 26 ns propagation delay for timing-sensitive applications. The wide operating temperature range makes it suitable for demanding industrial environments where thermal stability is critical.

Part Context

This part belongs to the LM5101 family of high-voltage gate drivers. It complements other variants like the LM5101AMX/NOPB which offers higher current ratings. The series provides solutions for various power management needs, focusing on reliable switching performance in compact surface-mount packages suitable for modern electronic designs.

Replacement Considerations

The LM5101M/NOPB serves as a public confirmed substitute option within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that any alternative component meets the same voltage and current requirements for the intended application.
