ADM1816-R23ARTZ-R7 Voltage Supervisor IC by Analog Devices Inc.

The ADM1816-R23ARTZ-R7 is a high-performance voltage supervisor integrated circuit (IC) designed and manufactured by Analog Devices Inc. This precision voltage monitoring device is engineered to ensure reliable operation and protection for microprocessors, digital systems, and other voltage-sensitive applications. With its compact SOT-23 package, the ADM1816-R23ARTZ-R7 is ideal for space-constrained applications that require accurate voltage supervision.

This voltage supervisor IC features a fixed threshold voltage of 2.3V, providing a precise monitoring solution for 2.5V power supplies and other low-voltage systems. The ADM1816-R23ARTZ-R7 asserts a reset signal whenever the monitored voltage drops below the 2.3V threshold, ensuring that the system can safely initialize during power-up, power-down, or brown-out conditions.

Key features of the ADM1816-R23ARTZ-R7 include:

• Fixed Threshold Voltage: Accurately monitors a 2.3V power supply line.
• Low Power Consumption: Ideal for battery-operated and portable devices, ensuring minimal impact on the system’s power budget.
• Reset Output: Provides an active-low reset signal, which remains asserted for a minimum of 140ms after the monitored voltage exceeds the threshold, allowing sufficient time for the system to stabilize.
• High Accuracy: Ensures reliable reset operation with a tight threshold accuracy that maintains system integrity.
• Wide Operating Temperature Range: Suitable for industrial and automotive applications with a temperature range from -40°C to +125°C.

The ADM1816-R23ARTZ-R7 is supplied in a small 3-lead SOT-23 package, which is RoHS compliant and designed for surface-mount technology (SMT), facilitating easy integration into a variety of electronic assemblies. With its robust design and high precision, this voltage supervisor IC is an excellent choice for safeguarding sensitive electronics against improper voltages, thus enhancing system reliability and longevity.

Whether used in microprocessor systems, portable devices, or complex digital systems, the ADM1816-R23ARTZ-R7 from Analog Devices Inc. provides the critical protection necessary to prevent data corruption and hardware damage due to unexpected voltage fluctuations.
