GENERAL DESCRIPTION

The ADM1169 Super Sequencer® 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 ADM1169 integrates a 12-bit ADC and

four 8-bit voltage output DACs. These circuits can be used to

implement a closed-loop margining system that enables supply

adjustment by altering either the feedback node or reference of

a dc-to-dc converter using the DAC outputs.

Watchdog function can be integrated in SE

Program software control of sequencing through SMBus

Complete voltage margining solution for 4 voltage rails

4 voltage output 8-bit DACs (0.300 V to 1.551 V) allow voltage

adjustment via dc-to-dc converter trim/feedback node

12-bit ADC for readback of all supervised voltages

Reference input (REFIN) has 2 input options

Driven directly from 2.048 V ( 0.25%) REFOUT pin

More accurate external reference for improved ADC

performance

Supply margining can be performed with a minimum of external

components. The margining loop can be used for in-circuit

testing of a board during production (for example, to verify

board functionality at −5% of nominal supplies), or it can be

used dynamically to accurately control the output voltage of

a dc-to-dc converter.

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 LQFP and 40-lead LFCSP packages

For more information about the ADM1169 register map, refer

to the AN-721 Application Note.

APPLICATIONS

Central office systems

Servers/routers

Multivoltage system line cards

DSP/FPGA supply sequencing

In-circuit testing of margined supplies
