• Manufacturer Part Number: ADM1169
• Description: Super Sequencer and Monitor with Margining Control and Non-Volatile Fault Recording
• Manufacturer: Analog Devices

Specifications of ADM1169

• # Supplies Monitored: 8
• Volt Monitoring Accuracy: 1%
• # Output Drivers: 8
• Fet Drive/enable Output: Both
• Voltage Readback: 12-bit ADC
• Supply Adj/margining: 12-bit ADC+4 DACs
• Package: 32 ld LQFP,40 ld LFCSP

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, there are eight
programmable outputs that 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 SE. 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 can 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 ADM1169 is controlled via configuration data that can be
programmed into an EEPROM. The entire configuration can
be programmed using an intuitive GUI-based software package
provided by Analog Devices, Inc.
