The ADM1065 is a high-performance supply sequencer and monitor that provides comprehensive monitoring and sequencing control for up to 10 supply voltages.
The ADM1065 Super Sequencer is a configurable supervisory and sequencing device that monitors up to ten supplies and provides ten programmable driver outputs, six of which can deliver up to 12 V for external N‑FET gate driving. It includes a sequencing engine with up to 63 states, SMBus interface, and a 256‑byte EEPROM for configuration.
The handbook details electrical specifications such as supply voltage ranges (VH 3.0 V‑14.4 V, VPx 3.0 V‑6.0 V), input impedance, output driver characteristics, reference output voltage, and absolute maximum ratings. Pin configurations for LFCSP and TQFP packages, thermal resistance, and ESD precautions are also provided.
