Power Management Integrated Circuit (PMIC) is an integrated circuit (IC) designed to power the electronics in a device. The PMIC is comprised of multiple components that work together to regulate and distribute power to the device. PMICs can be used for a variety of applications, from providing power to mobile phones, tablets and laptops, to powering industrial equipment and embedded systems. The PMIC can also be used to protect devices from electrical overloads by providing circuit protection. PMICs come in many different types and forms, such as simple power regulation circuits and complete integrated power management systems. Supervisors are PMICs that can detect and monitor conditions, control power usage and detect abnormalities.

APX803-23SRG-7 is a supervisor type of PMIC which has a wide application field and designed to protect systems against transient power disturbances. It is a very precise and precise low-voltage reset supervisor with open-drain/push-pull reset output and adjustable delays. This device incorporates an ultra-low on-resistance comparator, a precision voltage reference and a high-speed logic output. It is capable of detecting power-on reset due to one of the conditions such as power supply, overvoltage protection (OVP), brownout protection (BOP) and over temperature protection (OTP).

APX803-23SRG-7 is a single-channel reset supervisor with an adjustable delay and a programmable open-drain/push-pull reset output. The adjustable delay feature allows for easy set up and customization. The device is also equipped with an independent open-drain/push-pull output that can be used for a failed-safe operation. Additionally, the device is equiped with an over temperature shut down (OTSD) function which shuts down the internal oscillator and reset output in the event of over temperature.

APX803-23SRG-7 features an ultra-wide input voltage range from 1.5V to 5.5V. It has low power consumption and high accuracy, which makes it suitable for low power applications. It has an adjustable reset time (RST) range from 10ms to 1.8s after the input voltage drops below the reset threshold. An external capacitor is used to determine the reset time and can be adjusted to meet the needs of the application.

APX803-23SRG-7 has a wide variety of application fields including embedded systems, industrial equipment, automotive components, low-power systems, battery-powered equipment and consumer electronics. It provides a reliable power-on reset for a variety of electronic devices. The device can also be used for overvoltage protection, brownout protection and over temperature protection.

The working principle of APX803-23SRG-7 is relatively simple. It contains two main components; a voltage reference and a comparator. When power is applied to the device, the voltage reference is used to set the threshold level. When the input voltage falls below the threshold, the comparator triggers the reset output. This output is active for a predetermined amount of time determined by the value of an external capacitor connected to the devices' reset time (RST) pin. Once the reset time has elapsed, the device can reset itself or enter a stable state until a fault occurs, causing a reset output to be issued again.

In conclusion, APX803-23SRG-7 is a versatile and reliable PMIC. It can be used to protect systems from transient power disturbances and provides overvoltage, brownout, and over temperature protection. Its adjustable delay and open-drain/push-pull reset output make it suitable for a wide range of applications. Its low power consumption and high accuracy make it suitable for low power applications. Its working principle is relatively simple and provides a reliable power-on reset mechanism.
