Product details

12-channel PMBus system manager for power-supply sequencing

The MAX34460ETM+ is a 12-channel PMBus-compliant system manager that monitors and sequences up to twelve power-supply rails. It operates from a 3V to 3.6V supply, drawing 18 mA typical, and is specified over the -40°C to 85°C industrial temperature range.

The 3V to 3.6V supply range matches common 3.3V rails with margin. The 18 mA supply current is the total draw for the IC itself; the external rail-sense dividers and any pull-ups on the PMBus lines add to the system budget. Plan for that when sizing the 3.3V regulator feeding this part.

It is ROHS3 compliant.

Frequently asked questions

What is MAX34460ETM+ used for?

It is a 12-channel PMBus system manager for power-supply monitoring and sequencing — it tracks voltages, manages power-up/down sequencing, and communicates fault and status data over the PMBus interface. Typical applications include multi-rail boards in telecom, networking, servers, and industrial control.

Does MAX34460ETM+ support I2C programming?

The part uses the PMBus protocol, which is built on the I2C physical layer. Programming and monitoring are done over the PMBus interface using standard I2C-compatible signaling.
