The ADM1060 is a programmable supervisory/sequencing device that offers a single chip solution for multiple power supply fault detection and sequencing in communications systems.
The ADM1060 is a programmable supervisory/sequencing device designed for communications systems. It can detect faults on seven independent supplies—including one high‑voltage, four positive‑only, and two bipolar supplies—and sequence their power‑up and power‑down order.
Key features include a watchdog detector with a programmable timeout, four general‑purpose logic inputs, a programmable logic block array, nine programmable driver outputs (including charge‑pump high‑drive mode), 256‑byte EEPROM for configuration storage, and an industry‑standard I²C/SMBus interface for control.
