LTC1643ALIGN#PBF

Hot Swap Controllers Overview

The LTC1643ALIGN#PBF is a Hot Swap Voltage Controller designed for PCI-bus applications, manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.3V, 5V, and ±12V. The device is housed in a 16-SSOP package. Key electrical characteristics include latched fault protection, thermal limiting, and under-voltage lockout (UVLO). It features programmable current limit, fault timeout, and slew rate settings to manage power-up sequences and protect against overcurrent conditions.

Hot Swap Controllers Feature Summary

• Integrates latched fault protection and thermal limiting for robust system safety
• Supports under-voltage lockout (UVLO) to ensure stable operation during power transitions
• Offers programmable current limit, fault timeout, and slew rate configurations

Hot Swap Controllers Applications

• PCI-bus hot swap controller implementations
• Systems requiring controlled power-up sequencing
• Protection circuits for sensitive electronic loads

Hot Swap Controllers Procurement Notes

Verify the specific suffix ALIGN#PBF against the official Analog Devices datasheet to confirm pinout and functional compatibility. Ensure the procurement channel provides genuine components with traceability. Check for RoHS compliance documentation as required by your manufacturing standards. Confirm that the 16-SSOP package dimensions match your PCB footprint requirements before finalizing orders.

Hot Swap Controllers Selection Notes

Select this component when designing PCI-bus compatible systems requiring precise hot swap management. The programmable slew rate allows control of inrush current, while the latched fault feature ensures immediate shutdown upon critical errors. Consider the ±12V supply capability if your design utilizes dual-rail power architectures. Verify that the thermal limiting thresholds align with your board's thermal dissipation capabilities.

Hot Swap Controllers Part Context

This part belongs to the LTC1643 family of Hot Swap Controllers from Analog Devices. These controllers are specifically engineered to manage the insertion and removal of circuit boards while powered, preventing damage to the backplane and the inserted card. The ALIGN variant typically denotes specific mechanical or testing alignment specifications within the SSOP package line.
