LT4294HMS#PBF

Overview

The LT4294HMS#PBF is a hot-swap voltage controller manufactured by Analog Devices Inc., designed for IEEE 802.3bt Powered Device (PD) interface control. It operates within an input voltage range of 8 V to 60 V and features adjustable current limiting. The device supports single-channel operation with a supply current of 2 mA. It is housed in a DFN-10 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

Provides controlled power insertion for hot-swap applications
Supports IEEE 802.3bt Powered Device standards
Features adjustable current limit protection

Applications

IEEE 802.3bt Powered Device interface control
Hot-swap voltage regulation
Power distribution systems requiring controlled insertion

Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering, as availability may vary by region. Confirm that the DFN-10 package meets your PCB layout requirements. Ensure the operating temperature range up to +85°C aligns with your system's thermal design constraints. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when designing systems requiring compliant hot-swap capabilities for high-power Ethernet applications. The adjustable current limit allows customization for specific load requirements. Consider the DFN-10 package size for space-constrained designs. Verify compatibility with the target IEEE 802.3bt standard implementation. Ensure the 60 V maximum input rating exceeds the expected bus voltage under all operating conditions.

Part Context
