Product Overview: ADM811ZARTZ by Analog Devices Inc.

The ADM811ZARTZ is a high-quality supervisory circuit designed and manufactured by Analog Devices Inc., a leader in the semiconductor industry. This supervisory IC is specifically engineered to monitor power supply voltages and provide a reliable reset signal to microprocessors (µPs), ensuring the proper functioning of electronic systems upon startup, during operation, and under power fault conditions.

Key Features

• Voltage Monitoring: This device keeps a vigilant watch over the system's voltage levels. It is capable of monitoring a nominal voltage of 4.63V, which is crucial for applications that require a precise voltage threshold for safe operation.
• Reset Signal: Upon detection of an out-of-tolerance voltage level, the ADM811ZARTZ asserts a reset signal to the connected microprocessor. The reset signal remains asserted for a minimum of 140ms after the voltage level returns to an acceptable range, ensuring the system has adequate time to stabilize.
• Manual Reset Input: An additional feature of this supervisory circuit is the manual reset input, which allows for an external trigger to initiate a system reset. This is particularly useful for system maintenance or emergency situations.
• Low Power Consumption: Designed for power-sensitive applications, the ADM811ZARTZ boasts a low power consumption, making it an ideal choice for portable and battery-operated devices.
• Compact Packaging: The device comes in a compact SOT-143 package, which is beneficial for space-constrained applications without compromising performance.
