LTC4210-1IS6#TRPBF

The LTC4210-1IS6#TRPBF from Analog Devices (formerly Linear Technology) is a 6-pin SOT-23 hot swap controller. This IC enables safe insertion and removal of boards from live backplanes by controlling an external N-channel MOSFET. It operates with supply voltages ranging from 2.7V to 16.5V.

The controller provides an adjustable current limit with a circuit breaker timer for active current limiting and fast response to fault conditions. The LTC4210-1 variant offers automatic retry on overcurrent faults, while the LTC4210-2 variant provides latch-off. The device features an internal high-side switch driver and allows for an adjustable supply voltage power-up rate.

Key features include undervoltage lockout and adjustable overvoltage protection. The low-profile ThinSOT package makes it suitable for space-constrained applications. This component is ideal for use as an electronic circuit breaker or a high-side switch in industrial applications requiring robust power management.

Applications include safe board insertion and removal from live backplanes, adjustable analog current limit with circuit breaker functionality, and fast response to limit peak fault currents. It also supports adjustable supply voltage power-up rates and high-side drive for external MOSFET switches.
