APX810S05-26SR-7

Power system design requires selecting a supervisor IC (integrated circuit) that meets the application needs. A supervisor IC monitors power on/off and reset functions in a system. The APX810S05-26SR-7 is a supervisor IC that is specialized for battery-operated systems, such as cell phones, tablets, and other electronic devices. This article covers the APX810S05-26SR-7\'s application field, as well as its working principle.

Application Field

The APX810S05-26SR-7 is a low-power, battery-operated supervisor IC designed to support system power-up, reset, and battery backup. It is suitable for a variety of applications such as cell phones, tablets, PDAs, wearables, and industrial control devices. The low power consumption of the IC makes it ideal for battery-operated applications where power efficiency is a priority.

The APX810S05-26SR-7 supports system power-up and reset detection, and provides a solution for back-up power in battery-operated applications. It contains an internal voltage reference and monitors battery voltage, system voltage, and reset timeout periods to ensure consistent and safe power-on and reset behaviour. The IC also includes a programmable reset timeout circuit that allows for custom timing parameters specific to the application.

Working Principle

The APX810S05-26SR-7 uses a voltage regulator and internal power-on/reset circuit to control system power-up and reset behavior. The supervisor first monitors the system voltage and the battery voltage. When the system voltage reaches a certain voltage level (Vsys_threshold) it generates an "active high" signal, indicating the system is powered up and ready. The IC also contains an internal voltage reference that allows it to monitor the battery voltage and detect when the system voltage drops below a pre-programmed threshold (Vsys_backup). This threshold can be adjusted based on the application requirements.

The reset circuit in the APX810S05-26SR-7 monitors the reset timeout period. When the reset timeout period exceeds the pre-programmed threshold (RST_limit), the reset output goes active and the system is reset. The reset timeout period is adjustable based on the application requirements. The IC also features a programmable reset timeout circuit which allows for flexibility in setting power-on and reset timeouts.

The APX810S05-26SR-7 is a power supervisor IC that is designed for battery-operated applications. It provides an efficient solution for system power-up, reset detection, and battery backup. The IC features an internal voltage regulator and an adjustable reset timeout circuit. The APX810S05-26SR-7 is an ideal choice for any application where efficient and reliable system powering is required.
