Linear Comparators are a type of analog-to-digital conversion that measures an analog input to determine its value and then compares these inputs to a reference for the purpose of classification. The AP393SG-13 is an example of such a device. Its application and working principle will be described in this article.

The AP393SG-13 is a precision comparator with a low offset voltage that is intended for use in battery power systems. This device has a wide input voltage range of 1.3 to 13.2 volts and is able to measure as low as 30mV of differential input with excellent accuracy. This device also provides an ultra-low power threshold that is adjustable to suit various applications.

The AP393SG-13 has a wide range of applications in battery power systems as it is optimized for operation in battery-powered systems where minimal power consumption is desired. The device is ideal for battery-sizing and battery-monitoring applications. It is also useful for battery-level detection, battery-charging detection, and battery-lifetime prediction.

The AP393SG-13 working principle is based on the comparison of the battery voltage with a preset reference voltage. When the measured voltage falls below the predetermined reference voltage, the output pin of the device is toggled to 0V, indicating that the battery is low or has reached the “discharging” point. When the measured voltage is equal to or above the reference voltage, the output pin of the device is toggled to 5V, indicating that the battery is still within an acceptable voltage range.

The device also features form-C programmable setpoints that can be configured with either an external reference voltage or an internal reference voltage. This feature allows for precise control over the output signal and allows for a precise voltage threshold with adjustable hysteresis. Additionally, the device features an internal temperature sensor to enable accurate temperature compensation.

In summary, the AP393SG-13 is a precision comparator with a wide input voltage range that is ideal for use in battery power systems. The device has a wide range of applications in battery-sizing and monitoring and has a low offset voltage that enables accurate measurements. It also has form-C programmable setpoints to control the output signal with adjustable hysteresis and an internal temperature sensor for accurate temperature compensation.
