Product details

What this hot swap controller does

The Analog Devices ADM4210-1AUJZ-RL7 is a single-channel hot swap controller in a TSOT-6 package. It operates from 2.7 V to 16.5 V and draws 650 µA of supply current. Key programmable features include current limit, fault timeout, and turn-on voltage, giving you control over the ramp profile and the fault response. The UVLO (undervoltage lockout) ensures the controller stays off until the input rail is stable, preventing partial-power glitches during insertion. The -1 variant implements auto-retry: after a fault timeout, the controller automatically attempts to restart, which suits systems where a temporary overload is expected to clear on its own.

The part is ROHS3 compliant.

Frequently asked questions

What is the difference between ADM4210-1AUJZ-RL7 and ADM4210-2AUJZ-RL7?

The ADM4210-1AUJZ-RL7 uses auto-retry after a fault timeout, while the ADM4210-2AUJZ-RL7 uses a latched fault response. Both are pin-compatible, share the same TSOT-6 package, and operate from 2.7 V to 16.5 V.

Does the ADM4210-1AUJZ-RL7 have an internal switch?

No, the ADM4210-1AUJZ-RL7 does not have an internal switch. It drives an external N-channel MOSFET to control the power path.

What is the function of the UVLO feature in ADM4210-1AUJZ-RL7?

The UVLO (undervoltage lockout) keeps the controller disabled until the input supply rises above the programmed turn-on voltage, preventing the MOSFET from turning on during a brownout or slow ramp-up.
