ADM809SARTZ Voltage Supervisor by Analog Devices Inc.

The ADM809SARTZ is a highly reliable voltage supervisor device designed and manufactured by Analog Devices Inc., one of the leading companies in the semiconductor industry. This compact integrated circuit is engineered to monitor power supply voltages, ensuring that digital systems operate optimally within their power specifications. It is particularly suitable for microprocessor and microcontroller-based systems, where it can serve as a reset generator, providing a controlled initialization during power-up, power-down, or brown-out conditions.

The ADM809SARTZ operates by monitoring the Vcc voltage of a system. When this voltage drops below a preset threshold level, the device automatically generates a reset signal. The reset signal remains active for a minimum period, typically 140 ms, after Vcc rises above the reset threshold, ensuring that the system has sufficient time to stabilize before resuming operation. This feature is crucial for preventing system errors and data corruption that can occur if the system attempts to operate with an inadequate power supply.

This voltage supervisor comes in a compact SOT-23 package, making it an ideal choice for space-constrained applications. Its small footprint allows for easy integration into a wide range of electronic systems, from portable devices to complex digital circuits. The ADM809SARTZ operates over a wide temperature range, ensuring reliable performance in diverse operating environments.

Key features of the ADM809SARTZ include:

• Power supply monitoring at a preset threshold voltage
• Minimum 140 ms reset timeout period
• Low power consumption, enhancing battery life in portable applications
• Guaranteed reset output down to Vcc = 1.0 V
• Push-pull active-low reset output
• Wide operating temperature range
• Compact SOT-23 package for space-saving design

Whether you're designing a consumer electronic device, an industrial control system, or a sensitive communication module, the ADM809SARTZ provides a reliable solution for managing your system's power integrity. With its precision voltage monitoring and robust reset functionality, this voltage supervisor from Analog Devices Inc. is a critical component for maintaining the stability and reliability of your electronic systems.
