GENERAL DESCRIPTION

The ADM1060 is a programmable supervisory/sequencing device that offers a single chip solution for multiple power supply fault detection and sequencing in communications systems.

FEATURES

Faults detected on 7 independent supplies

1 high voltage supply (2 V to 14.4 V)

4 positive voltage only supplies (2 V to 6 V)

2 positive/negative voltage supplies

(+2 V to +6 V and –2 V to –6 V)

Watchdog detector input—timeout delay programmable

from 200 ms to 12.8 sec

4 general-purpose logic inputs

Programmable logic block—combinatorial and sequencing

logic control of all inputs and outputs

9 programmable output drivers:

Open collector (external resistor required)

Open collector with internal pull-up to VDD

Fast internal pull-up to VDD

Open collector with internal pull-up to VPn

Fast internal pull-up to VPn

Internally charge-pumped high drive (for use with

external N-channel FETs—PDOs 1 to 4 only)

EEPROM—256 bytes of user EEPROM

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VPn, VH = 1 V

APPLICATIONS

Central office systems

Servers
