ADM1168
Super Sequencer and Monitor with Nonvolatile Fault Recording
Top
Overview
Features and Benefits
- 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 - 16 event deep black box nonvolatile fault recording
- 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
- Complete supervisory and sequencing solution for up to 8 supplies
- 8 programmable driver outputs, PDO1 to PDO8 (PDOx)
Open-collector with external pull-up
Push/pull output, driven to VDDCAP or VPx - Sequencing engine (SE) implements state machine control of PDO outputs
State changes conditional on input events
Enables complex control of boards - Device powered by the highest of VPx, VH for improved redundancy
- User EEPROM: 256 bytes
- See datasheet for additional features
Product Details
The ADM1168 Super Sequencer® is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems.
The device also provides up to eight programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of-window faults on up to eight supplies. In addition, eight programmable outputs can be used as logic enables. Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an NFET that can be placed in the path of a supply.
The logical core of the device is a sequencing engine. This state machine-based construction provides up to 63 different states. This design enables very flexible sequencing of the outputs based on the condition of the inputs.
A block of nonvolatile EEPROM is available that can be used to store user-defined information and may also be used to hold a number of fault records that are written by the sequencing engine defined by the user when a particular fault or sequence occurs.
The ADM1168 is controlled via configuration data that can be programmed into an EEPROM. The whole configuration can be programmed using an intuitive GUI-based software package provided by Analog Devices, Inc.
For more information about the ADM1168 register map, refer to the AN-721 Application Note.
