ADM1184ARMZ-REEL7

The ADM1184ARMZ-REEL7 is an integrated 4-channel voltage monitor and sequencer, packaged in a reel format for automated assembly processes. This versatile component offers a range of advanced features to ensure reliable and efficient power management in electronic devices.

Key Features:

1. 4-Channel Voltage Monitoring: The ADM1184ARMZ-REEL7 can monitor up to four independent voltage rails, providing comprehensive power supervision for multi-rail systems. Each channel includes a precision comparator with a built-in 0.6V reference voltage source, offering accuracy of ±0.8% in worst-case scenarios.
2. Programmable Thresholds: Users can set the trip points for the monitored power rails by connecting external resistor networks to the VIN1, VIN2, VIN3, and VIN4 pins. This provides flexibility in configuring the power monitoring thresholds to suit specific application requirements.
3. Power-Good Output: The PWRGD pin serves as a general power-good output, indicating that all monitored power rails are above their respective threshold values. This signal can be used to initiate system startup or to provide an alert when power conditions fall below acceptable levels.
4. Sequencing and Enable Outputs: The ADM1184ARMZ-REEL7 includes three open-drain enable outputs (OUT1, OUT2, and OUT3), which can be used to control the power-up sequence of external loads. These outputs depend on the associated VINx inputs and are disabled if the monitored power rail falls below its programmed threshold.
5. Delay Timer: An internal 190ms (typical) delay timer is provided on the PWRGD output to debounce power supply transitions and prevent false triggering.
6. Compact Size and High Integration: Packaged in a 10-pin MSOP, the ADM1184ARMZ-REEL7 offers a compact size while integrating all necessary power monitoring and sequencing functionality.
7. Wide Operating Range: The IC operates over a wide supply voltage range of 2.7V to 5.5V, making it suitable for a variety of applications.

Applications:

The ADM1184ARMZ-REEL7 is ideal for a range of applications, including:

• Power supply monitoring and sequencing in telecommunications equipment
• Microprocessor systems and PC/servers requiring reliable power management
• Industrial and automotive electronics where precise power supervision is critical

In summary, the ADM1184ARMZ-REEL7 is a highly integrated and versatile 4-channel voltage monitor and sequencer, packaged in a reel format for automated assembly. Its advanced features, including programmable thresholds, power-good output, sequencing and enable outputs, and compact size, make it an ideal choice for applications requiring reliable and efficient power management solutions.
