Examples include consumer electronic products, alarm systems, security systems, safety systems, and battery-powered equipment. Furthermore, its 8-pin small-package feature means it can be used in a variety of applications without adding excessive hardware cost.

Working Principle of ADM8693ARN

The heart of the ADM8693ARN is a proprietary Voltage Supervisor IC (VSI). This VSI consists of a voltage monitor, a voltage reference, and a precision voltage detection circuit. The voltage monitor continuously monitors the voltage for variations and will trip an internal circuit upon an over-voltage or an under-voltage event. The voltage reference is designed to provide a stable reference voltage for the voltage detection circuit.

The precision voltage detection circuit is designed to detect any change in the voltage with very high accuracy. The accuracy of the VSI is 0.5% of the full-scale voltage reading, meaning that the voltage being monitored must stay within the range +/-0.5%, +/-1%, or +/-2% window. When the VSI trips, it will trigger an output signal which can be used to notify the system.

The ADM8693ARN can be configured to trigger an output signal based upon the monitored voltage level. The output signal can either be a logic high signal, logic low signal, or a pulse signal. The output signal can be programmed to be either a single-shot pulse signal or a continuous signal. The signal can also be programmed to be active low, active high, or open collector.

In addition to voltage monitoring, the ADM8693ARN also provides an internal voltage reference for use in applications such as battery management and power supply monitoring. The reference voltage is adjustable from 1.8V to 4.5V and can be set to any voltage within its range. The adjustable range allows the ADM8693ARN to be used in applications requiring a precise reference voltage.

Conclusion

ADM8693ARN is a low-cost Digital-Output Micropower Supervisors which is cost-effective, temperature-stable, efficient, and suitable for a wide range of application fields. It provides voltage monitoring and reference voltages to a variety of embedded systems, including microprocessor and microcontroller systems, battery management systems, power-supply monitoring applications, and a variety of sensing applications. It is capable of detecting voltages within a +/-0.5%, +/-1%, or +/-2% window and can be programmed to generate an output signal based upon the monitored voltage level.
