LM5100CSD

Overview

The LM5100CSD is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers designed to control N-channel MOSFETs in power conversion applications. The device operates with a supply voltage range of 9 V to 14 V and supports bootstrap supply voltages up to 118 V. It features a non-inverting logic configuration and is housed in a compact 10-pin WSON package, suitable for surface-mount assembly.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge topologies
• Supports high-voltage operation with bootstrap supply capability up to 118 V
• Features non-inverting logic inputs for straightforward interface with control signals
• Designed for efficient driving of N-channel MOSFETs in power management circuits

Applications

• High-voltage DC-DC converters
• Half-bridge power stages
• Motor drive circuits
• Industrial power supplies

Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free status and exact pinout compatibility. Confirm current lifecycle status as some variants may be obsolete. Ensure the package type matches the PCB footprint requirements. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components.

Selection Notes

Select this component for applications requiring isolated or floating high-side drive capabilities within a half-bridge configuration. Consider the 1A output current capability and propagation delay characteristics relative to switching frequency requirements. Evaluate thermal performance within the WSON package for the intended power dissipation levels.

Part Context

The LM5100 series belongs to Texas Instruments' portfolio of high-voltage gate drivers. These devices are engineered for robust performance in demanding power electronics environments. The CSD variant specifically denotes the 10-pin WSON package option, distinguishing it from other package types like SOIC or MSOP available in the same functional family.

Replacement Considerations

Check for direct substitutes such as LM5100CSD/NOPB for lead-free compliance. Verify functional equivalence with LM5101 if level-shifting requirements differ. Consult official substitution guides for pin-compatible alternatives with updated manufacturing statuses.
