ADM809JARTZ-REEL7 - Voltage Supervisor by Analog Devices Inc.

The ADM809JARTZ-REEL7 is a highly reliable voltage supervisor component designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This component is specifically engineered to monitor power supply voltages, ensuring that digital systems operate optimally and are protected from undesirable voltage conditions. It is a crucial addition to any system that requires precise voltage monitoring and reset functionalities.

This voltage supervisor is available in a compact SOT-23 package, making it an ideal choice for space-constrained applications. The ADM809JARTZ-REEL7 is provided in tape and reel form, denoted by the 'REEL7' suffix, facilitating efficient assembly processes for high-volume production requirements.

The device features a reset output during power-up, power-down, and brownout conditions. Upon detection of a voltage that falls below the preset threshold, the ADM809JARTZ-REEL7 asserts a reset signal that holds the microprocessor in a reset state for a minimum of 140ms after the supply voltage exceeds the reset threshold level. This ensures that the system has sufficient time to stabilize before the processor starts operating, which is critical for maintaining system integrity and preventing data corruption.

Key specifications of the ADM809JARTZ-REEL7 include:

• Supply Voltage Range: 2.5V to 5.5V
• Reset Threshold Voltage: Precisely set at 4.38V
• Reset Output Stage: Active Low, Open Drain
• Minimum Power-On Reset Pulse Width: 140ms
• Low Supply Current: Ideal for battery-powered applications
• Temperature Range: -40°C to +85°C, suitable for industrial environments

With its precision voltage monitoring and robust reset functionality, the ADM809JARTZ-REEL7 is an essential component for ensuring the reliable operation of microprocessor-based systems. Whether used in personal electronics, communication devices, or industrial control systems, this voltage supervisor provides peace of mind by safeguarding against power supply anomalies.

For designers and engineers looking for a dependable solution to protect their digital systems from voltage irregularities, the ADM809JARTZ-REEL7 from Analog Devices Inc. offers the performance and reliability that is synonymous with the brand's reputation in the semiconductor industry.
