The ADM1185 is an integrated, 4-channel, voltage monitoring and sequencing device. A 2.7 V to 5.5 V power supply is required on the VCC pin to power the device.

Four precision comparators monitor four voltage rails. All comparators have a 0.6 V reference with a worst-case accuracy of 0.8%. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the trip points for the monitored supply rails.

A digital core interprets the status of the comparator outputs.

Internal time delays can be used for sequencing the startup of subsequent power supplies enabled by the outputs. Supplies falling out of range are also detected and, as a result, appropriate outputs are disabled.

The ADM1185 has four open-drain outputs. In a typical configuration, OUT1 to OUT3 are used to enable power supplies, while PWRGD is a common power-good output, indicating the status of all monitored supplies.

The ADM1185 is available in a 10-lead mini small outline package (MSOP).

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
