Overview
Data Sheet Super Sequencer and Monitor with Nonvolatile Fault Recording ADM1168 FEATURES Complete supervisory and sequencing solution for up to 8 supplies 16 event deep black box nonvolatile fault recording 8 supply fault detectors enable supervision of supplies to <0.
5% accuracy at all voltages at 25°C <1.
0% accuracy across all voltages and temperatures 4 selectable input attenuators allow supervision of supplies to 14.
4 V on VH 6 V on VP1 to VP3 (VPx) 4 dual-function inputs, VX1 to VX4 (VXx) High impedance input to supply fault detector with thresholds between 0.
573 V and 1.
375 V General-purpose logic input 8 programmable driver outputs, PDO1 to PDO8 (PDOx) Open-collector with external pull-up Push/pull output, driven to VDDCAP or VPx Open-collector with weak pull-up to VDDCAP or VPx Internally charge-pumped high drive for use with external NFET (PDO1 to PDO6 only) Sequencing engine (SE) implements state machine control of PDO outputs State changes conditional on input events Enables complex control of boards Power-up and power-down sequence control Fault event handling Interrupt generation on warnings Watchdog function can be integrated in SE Program software control of sequencing through SMBus Device powered by the highest of VPx, VH for improved redundancy User EEPROM: 256 bytes Industry-standard 2-wire bus interface (SMBus) Guaranteed PDO low with VH, VPx = 1.
