ADM803SAKS-REEL7 - Supervisory Circuit from Analog Devices Inc.

The ADM803SAKS-REEL7 is a highly reliable supervisory circuit designed by Analog Devices Inc., a leader in high-performance semiconductors. This compact component plays a crucial role in monitoring power supply voltages in microprocessor systems, helping to ensure that the system operates effectively under varying power conditions. The ADM803SAKS-REEL7 is specifically engineered to maintain system integrity through its reset and monitoring capabilities.

This supervisory circuit is notable for its precision voltage monitoring feature, which allows it to keep a close watch on the system's power rails. When the monitored voltage falls below the minimum voltage threshold, the ADM803SAKS-REEL7 asserts a reset signal, which remains active until the voltage recovers to an acceptable level and a specified period has passed. This reset output ensures that the microprocessor and other critical components are reset properly, preventing any malfunction due to insufficient power.

The ADM803SAKS-REEL7 is offered in a compact SOT-23 package, which is highly suitable for space-constrained applications. Its small size makes it an ideal choice for portable devices where board space is at a premium. Moreover, the device is available in tape and reel packaging (REEL7), which facilitates efficient assembly processes, especially for high-volume production.

Key features of the ADM803SAKS-REEL7 include:

• Accurate monitoring of 3.08V power supply voltages
• Low power consumption, enhancing overall system efficiency
• Active-low reset output
• 140 ms minimum power-on reset pulse width
• Guaranteed reset output from Vcc = 1V
• Push-pull reset output (no external pull-up resistor required)
• Wide operating temperature range

Applications for the ADM803SAKS-REEL7 are diverse and include portable devices, computers, controllers, and any other systems that require reliable voltage monitoring and reset functions. With its precision and low power consumption, this supervisory circuit ensures that systems remain operational and protected against the dangers of undervoltage conditions, making it a trusted component in safeguarding electronic systems.
