Description



Features:

Complete supervisory and sequencing solution for up to 10 supplies
10 supply fault detectors enable supervision of supplies to better than 1% accuracy
5 selectable input attenuators allow supervision of supplies up to
14.4 V on VH
6 V on VP1 to VP4
5 dual-function inputs, VX1 to VX5
High impedance input to supply fault detector with thresholds between 0.573 V and 1.375 V
General-purpose logic input
10 programmable output drivers, PDO1 to PDO10
Open collector with external pull-up
Push/pull output, driven to VDDCAP or VPn
Open collector with weak pull-up to VDDCAP or VPn
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
Complete voltage margining solution for 6 voltage rails 6 voltage output, 8-bit DACs (0.300 V to 1.551 V) allow voltage
adjustment via dc-to-dc converter trim/feedback node

Description

The ADM1063 is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. In addition to these functions, the ADM1063 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed-loop margining system, which enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs.
