ADM1185

Quad Voltage Monitor and Sequencer
Manufactured by:

Product Details

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).

Product Details

The EVAL-AD7928SDZ is a full featured evaluation board that allows the user to easily evaluate all the features of the AD7928 analog-to-digital converter (ADC). The evaluation board can be controlled by the

EVAL-SDP-CB1Z SDP board via a 120-way SDP connector (J102). The SDP board allows the evaluation board to be controlled through the USB port of a PC using the AD7928 evaluation software, which is available for download from the product page or from the installer CD included in the evaluation board kit.

On-board components include the following:
  • ADP1613: 20 V, 2 A, step up, dc-to-dc regulator
  • ADP7104ARDZ-5.0: 5 V, low noise LDO
  • AD780: high precision, band gap voltage reference
  • ADG3308: bidirectional logic level translator
  • AD8022: dual high speed, low noise operational amplifier
  • AD8066: dual FastFET™, low noise operational amplifier
  • ADA4000-2: dual low cost, precision JFET input operational amplifier
  • ADM1185: quad voltage monitor and sequencer
  • ADP3303: high accuracy anyCAP®, 200 mA, low dropout linear regulator
