LTC1643AHIGN#TRPBF

Hot Swap Controllers Overview

The LTC1643AHIGN#TRPBF is a hot swap voltage controller designed for motherboard applications. It integrates four independent channels with internal switches, supporting both high-side and low-side control. The device operates within a supply voltage range of 3.3V, 5V, or ±12V. Key programmable features include current limit, fault timeout, and slew rate settings. The maximum output current capability is specified at 200mA or 500mA depending on the configuration.

Hot Swap Controllers Feature Summary

• Integrates four independent hot swap channels with internal switches for comprehensive power management
• Supports programmable current limiting, fault timeout durations, and controlled slew rates
• Compatible with multiple supply voltage configurations including 3.3V, 5V, and ±12V systems

Hot Swap Controllers Applications

• Motherboard power distribution
• Hot swap circuit protection
• Multi-channel power sequencing

Hot Swap Controllers Procurement Notes

Verify the specific suffix (TRPBF) indicates tape-and-reel packaging and lead-free compliance. Confirm the operating temperature grade matches the 'A' designation in the part number. Ensure the selected variant supports the required channel count and internal switch topology for the target design.

Hot Swap Controllers Selection Notes

Select this component when four independent hot swap channels are required on a single IC. Verify that the internal switch architecture meets the load requirements. Check compatibility with the system's supply voltage rails. Ensure the programmable parameters can be set to protect the connected loads during insertion and removal events.

Hot Swap Controllers Part Context

This part belongs to the LTC1643 family of hot swap controllers from Analog Devices. It is distinct from evaluation boards like the DC1643A and other controllers such as the LTC1647-1. The device is specifically engineered for multi-channel applications requiring integrated switching capabilities.

Hot Swap Controllers Replacement Considerations

Check for direct pin-compatible substitutes within the LTC1643 series. Verify if alternative hot swap controllers offer similar channel counts and internal switch configurations. Ensure any replacement maintains the same supply voltage and programmability features.
