ADM1166ASUZ-REEL7

The ADM1166ASUZ-REEL7 is a highly versatile and configurable power supervisor/sequencer IC that provides a comprehensive solution for power monitoring and sequencing in multi-power systems. Packaged in a reel format, this component is designed for use in automated assembly processes and offers a range of advanced features to meet the needs of modern electronic devices.

Key Features:

1. Power Monitoring and Sequencing: The ADM1166ASUZ-REEL7 can monitor up to 10 power supplies and control their sequencing, ensuring safe and reliable power-up and power-down procedures. This helps to protect sensitive components and extend the lifespan of electronic devices.
2. Integrated ADC and DAC: The IC integrates a 12-bit analog-to-digital converter (ADC) and six 8-bit voltage output digital-to-analog converters (DACs). These circuits enable closed-loop margining systems, allowing for precise power adjustments by modifying feedback nodes or altering the reference voltage of DC-DC converters via DAC outputs.
3. Margining Loop: The margining loop feature can be used for in-circuit testing during production, such as verifying the functionality of circuit boards at power supply voltages 5% below the nominal voltage. It can also be used dynamically to accurately control the output voltage of DC-DC converters.
4. Fault Recording and Detection: The ADM1166ASUZ-REEL7 offers a 16-event deep black box non-volatile fault recording function and 10 power failure detectors. The power monitoring accuracy is less than 0.5% at all voltages and 25°C, and less than 1.0% at all voltages and temperatures.
5. Programmable Outputs: The IC includes 10 programmable driver outputs (PDOs) that can be configured as open-collector/drain or push-pull outputs. This provides flexibility in interfacing with various loads and systems.
6. Compact Size and High Integration: Packaged in a 48-pin thin quad flat pack (TQFP) with a 7x7mm footprint, the ADM1166ASUZ-REEL7 offers a compact size while integrating a range of advanced features.
7. Wide Operating Range: The IC operates over a wide temperature range of -40°C to +85°C and supports input voltages up to 14.4V (VH) and 6V (VPx).

Applications:

The ADM1166ASUZ-REEL7 is ideal for a range of applications, including:

• Central office systems
• Servers and routers
• Line cards in multi-voltage systems
• DSP/FPGA power sequencing
• In-circuit testing for margining power supplies

In summary, the ADM1166ASUZ-REEL7 is a highly configurable and versatile power supervisor/sequencer IC that offers a range of advanced features to meet the needs of modern electronic devices. Its integration of ADC and DAC circuits, fault recording and detection capabilities, and compact size make it an ideal choice for applications requiring precise power monitoring and sequencing.
