LTC1646IGN#PBF

Hot Swap Controllers Overview

The LTC1646IGN#PBF is a dual-channel hot-swap voltage controller manufactured by Analog Devices Inc. Designed for CompactPCI applications, it manages power insertion and removal for systems requiring 3.3V or 5V supplies. The device operates within a supply voltage range of 2.7 V to 7 V and features programmable current limiting. It is housed in a 16-lead SSOP package and supports surface-mount installation with an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent control of two power rails
• Programmable current limiting to protect against overcurrent conditions
• Compliance with CompactPCI Hot-Swap specification PICMG 2.1 requirements

Hot Swap Controllers Applications

• CompactPCI backplane power management
• Hot-swap controller for 3.3V and 5V plugin boards
• Power isolation in compact PCI bus systems

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific suffix IGN#PBF matches the required SSOP-16 package and lead-free specifications. Check for restricted availability status as indicated by manufacturer notices. Ensure compatibility with existing PCB footprints and thermal management designs before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing CompactPCI systems requiring dual hot-swap capabilities. It is suitable for applications needing precise power sequencing and protection for 3.3V and 5V rails. Consider the SSOP-16 package constraints and the 2.7V to 7V input range. Evaluate if the integrated current limiting meets system protection requirements without external components.
