Specifications of ADM1068ASTZ

Features of ADM1068ASTZ

* Complete supervisory and sequencing solution for up to 8 supplies
* 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 N-FET (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 = 1.2 V
* Available in 32-lead 7 mm × 7 mm LQFP
