LM5101AMX/NOPB

Overview

The LM5101AMX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side drivers capable of driving N-channel MOSFETs with peak output currents of 3A. The device operates within a supply voltage range of 9V to 14V and supports input logic levels compatible with TTL standards. Key electrical parameters include a maximum propagation delay of 26ns, rise time of 430ns, and fall time of 260ns. It is housed in an 8-SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side gate drive outputs for half-bridge configurations
• Supports non-inverting logic inputs compatible with standard TTL thresholds
• Integrated under-voltage lockout protection ensures safe switching operations

Applications

• High-side and low-side power MOSFET switching control
• Half-bridge DC-DC converter topologies
• Motor driver interface circuits

Procurement Notes

Verify the specific suffix 'AMX' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the component meets RoHS compliance requirements as indicated by the 'NOPB' designation. Ensure the selected distributor provides genuine Texas Instruments products to avoid counterfeit risks associated with high-volume power management ICs.

Selection Notes

Select this component when designing circuits requiring independent control of high-side and low-side switches with moderate current drive capabilities. The 8-SOIC package offers a balance between thermal performance and board space efficiency. Consider the 9V to 14V supply requirement when designing the bias circuitry for the driver stage.

Part Context

This part belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. It is designed specifically for applications requiring robust switching of N-channel MOSFETs in harsh environments. The device integrates essential protection features to enhance system reliability in power conversion and motor control applications.

Replacement Considerations

Direct substitutes within the same family include the LM5101CMA/NOPB and LM5101ASD/NOPB. Verify pin compatibility and electrical specifications before swapping components to ensure circuit functionality remains intact.
