Description

The ADM811RARTZ is a voltage supervisor integrated circuit designed to monitor power supply levels in various electronic applications. It features a precision voltage monitoring capability, which allows it to detect under-voltage and over-voltage conditions. The device operates within a wide voltage range, typically from 1.5V to 5.0V, and is designed to ensure that critical systems remain operational by providing timely alerts when voltage levels fall outside of specified thresholds.
The ADM811RARTZ includes a reset output, which can be used to reset microcontrollers or other digital devices in response to voltage anomalies. Its low power consumption makes it suitable for battery-operated devices, and it comes in a compact package, facilitating integration into space-constrained designs.
Overall, the ADM811RARTZ enhances the reliability and stability of electronic systems by ensuring that they operate within safe voltage limits, making it an essential component in power management solutions.

Features

The ADM811RARTZ is a precision voltage supervisor designed for monitoring power supply voltages. Key features include:
1. Voltage Monitoring: It provides a set threshold voltage for power supply monitoring, helping to prevent system failures.
2. Reset Output: The output is active low, ensuring a reset signal is issued when the monitored voltage falls below the threshold.
3. Tight Tolerance: It offers a voltage threshold accuracy of ±2.5%, ensuring reliable operation.
4. Low Supply Current: The device features low power consumption, making it suitable for battery-operated applications.
5. Fast Response Time: It responds quickly to voltage changes, which enhances system reliability.
6. Temperature Range: Operates over a wide temperature range, typically from -40°C to +125°C.
7. Multiple Options: Available with various reset thresholds and timeout options to suit different applications.
These features make the ADM811RARTZ ideal for use in microcontroller-based systems, ensuring they operate within safe voltage limits.

Package

The ADM811RARTZ comes in a 5-lead SOT-23 package type.

Pinout

The ADM811RARTZ is a supervisory circuit with a pin count of 5. Its primary functions include voltage monitoring and reset generation. Specifically, it provides a reset signal to microcontrollers and processors in the event of a power failure or brownout condition.
### Pin Functions:
1. VDD (Pin 1): Supply voltage input.
2. GND (Pin 2): Ground reference.
3. RESET (Pin 3): Active LOW reset output; it goes low when VDD falls below the reset threshold.
4. SENSE (Pin 4): Monitors the supply voltage and triggers the reset if below the specified threshold.
5. NC (Pin 5): No connection; this pin is not used.
The ADM811RARTZ is commonly used in various applications to ensure reliable operation of digital systems by providing a reset signal during low voltage conditions.
