LTC4230CGN#PBF

Hot Swap Controllers Overview

The LTC4230CGN#PBF is a hot swap voltage controller manufactured by Analog Devices Inc. It integrates three independent channels for managing power insertion and removal in live backplane systems. The device supports an operating supply voltage range of 1.7V to 36V. Key electrical parameters include a maximum supply voltage of 36V, a minimum supply voltage of 2.7V (typical operational range), and an operating supply current of 1.8 mA. It features adjustable current limiting and operates within a temperature range of 0°C to +70°C. The component is housed in a 20-lead SSOP package with a width of 3.90mm.

Hot Swap Controllers Feature Summary

• Integrates three independent hot swap control channels for multi-rail power distribution management.
• Supports programmable fault handling including auto-retry, latched faults, and configurable timeout periods.
• Provides comprehensive protection mechanisms such as overvoltage protection, undervoltage lockout, and adjustable slew rate control.

Hot Swap Controllers Applications

• General purpose hot swap applications requiring multiple channel control
• Telecommunications equipment power distribution boards
• Industrial control systems with live insertion requirements

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the SSOP-20 package availability matches your PCB footprint requirements. Check current stock levels as distribution may vary. Ensure the 0°C to 70°C commercial temperature grade meets your environmental specifications before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when three-channel hot swap control is required within a single IC. Compare against single-channel alternatives if fewer rails are needed. Verify that the 1.8mA supply current fits your system's power budget. Ensure the 36V maximum input rating aligns with your bus voltage levels. Consider the SSOP-20 package constraints during layout planning.
