The ADM1069 is a power sequencer with margining control that provides a complete supervisory and sequencing solution for up to 8 supplies. It has 8 programmable driver outputs, 4 selectable input attenuators, 4 dual-function inputs, 1 high impedance input to supply fault detector, and 1 general-purpose logic input.
The ADM1069 Super Sequencer provides complete supervisory and sequencing for up to eight supplies. It includes fault detectors with <0.5 % accuracy, programmable driver outputs, a 12‑bit ADC for voltage read‑back, and four 8‑bit DACs for closed‑loop margining. The device is controlled via an SMBus interface and can be programmed through an on‑chip EEPROM.
Typical applications include central office systems, servers/routers, multivoltage line cards, DSP/FPGA supply sequencing, and in‑circuit testing of margin‑adjusted supplies. The part is offered in 32‑lead LOFP and 40‑lead LFCSP packages and operates from –40 °C to +85 °C.
