LM5101AM

Overview

The LM5101AM is a high-voltage half-bridge gate driver manufactured by Texas Instruments, designed to drive N-channel power MOSFETs and IGBTs. It integrates independent high-side and low-side drivers within an SOIC-8 package. The device supports a supply voltage range of 9 V to 14 V and delivers a peak output current of 3 A. Key electrical parameters include a maximum propagation delay of 26 ns, rise time of 430 ns, and fall time of 260 ns. It operates reliably across a temperature range of -40°C to +125°C with TTL-compatible logic inputs.

Feature Summary

• Integrates independent high-side and low-side drivers for half-bridge configurations
• Provides 3 A peak source and sink output current capability
• Features internal under-voltage lockout protection for reliable operation

Applications

• Motor control systems
• Industrial power supplies
• Inverter circuits

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference datasheet revisions to validate electrical characteristics before integration into final designs.

Selection Notes

Select this component when a 3 A drive current is required for high-side and low-side switching applications. The SOIC-8 package offers a compact solution for space-constrained designs. Consider the 26 ns propagation delay and 430/260 ns transition times for timing-sensitive PWM signals in motor or power conversion topologies.

Part Context

The LM5101AM belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. This series includes variants with different current capabilities, such as the 2 A LM5101B and 1 A LM5101C models. All share similar architectural features but differ in output drive strength and specific performance metrics defined in their respective datasheets.
