Product details

Programmable features and fault handling

Three programmable parameters — current limit, fault timeout, and turn-on voltage (UVLO) — let the designer tailor the controller to the load without changing the external FET. The latched fault behaviour means a sustained overcurrent or short shuts the FET off and holds it off until the input is cycled or the part is reset; no automatic retry, which is the right behaviour for a backplane slot that should stay off until a human clears the fault.

The TSOT-23-8 package (SOT-23-8 Thin variant) is a surface-mount footprint common for small hot swap controllers. Check the MSL level before the reflow — the datasheet will state the floor life, and if it is MSL 1 you can run it straight off the reel; higher levels need a bake before the oven.

ROHS3 compliance is confirmed, so no exemption paperwork is needed for EU-market builds.

Frequently asked questions

Is ADM1170-2AUJZ-RL7 RoHS compliant?

Yes, the ADM1170-2AUJZ-RL7 is ROHS3 compliant, which covers the EU RoHS exemption list and is accepted in most global markets without additional documentation.

Does ADM1170-2AUJZ-RL7 have an I2C interface?

Yes, the controller includes an I²C interface for reading current and voltage telemetry, which lets a system monitor the load without adding a separate ADC.

Does the ADM1170-2AUJZ-RL7 have internal power switches?

No, the ADM1170-2AUJZ-RL7 does not have an internal switch. It drives an external N-channel MOSFET, so the FET's Rds(on) and current rating must be selected to match the load.

When sourcing ADM1170-2AUJZ-RL7, what's the closest functional second-source?

The ADM1176-2ARMZ-R7 is a close functional peer — same I²C interface, same programmable features, same temperature range — but it adds a monitoring function. The ADM4210-2AUJZ-RL7 is a simpler controller without I²C, which may suit designs that do not need telemetry.
