ADM1266 Cascadable Super Sequencer

The ADM1266 Super Sequencer® is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in systems with up to 17 supplies. For systems with more supplies (up to 257), the operation of up to 16 ADM1266 devices can be synchronized through a proprietary 2-wire interface (interdevice bus). The sequenc.
