LT4220IGN#TRPBF

LT4220IGN#TRPBF Description

The LT4220IGN#TRPBF from Analog Devices Inc. is a dual-channel hot swap controller designed for general-purpose applications requiring robust power management. Operating within a 2.7V to 16.5V supply range, it ensures safe insertion and removal of live boards, protecting sensitive components from inrush currents and voltage transients. Packaged in a 16SSOP and available in Tape & Reel (TR), this RoHS3-compliant device is ideal for high-reliability surface-mount designs. Its 2.7 mA supply current minimizes power overhead, while MSL 1 (Unlimited) rating ensures long shelf life without moisture sensitivity concerns.

LT4220IGN#TRPBF Features

• Dual-Channel Control: Independently manages two power paths, enhancing system flexibility.
• Programmable Protection: Features Auto Retry, Fault Timeout, Latched Fault, and UVLO for tailored fault responses.
• Wide Voltage Range: Supports 2.7V–16.5V, accommodating diverse power rails.
• Low Quiescent Current: 2.7 mA minimizes energy waste in always-on systems.
• No Internal Switches: Allows external FET selection for optimized RDS(ON) and thermal performance.
• Robust Compliance: EAR99, REACH Unaffected, and ROHS3 Compliant, meeting global regulatory standards.
