It is an ideal choice for applications that require a low power reset, which makes it suitable for medical devices, industrial control systems, computer peripherals, embedded systems, automotive electronics, and telecom/networking devices.

The APX803S05-40SR-7 has a low operating voltage of 0.9 to 5.5V. It provides a wide operating temperature range from -40°C to 125°C. It is a highly reliable device, with an extended temperature range and high immunity to interference. It also complies with RoHS and Halogen Free standards.

The APX803S05-40SR-7\'s high reliability, low supply current, low operating voltage, and wide operating temperature range makes it ideal for a variety of applications.

Working Principle

The APX803S05-40SR-7 provides an adjustable reset time window of 200ms-1s, plus an adjustable reset threshold voltage. The reset time window can be adjusted with an external resistor. The reset threshold voltage can be adjusted through a potentiometer or via I2C.

The APX803S05-40SR-7 monitors the power supply voltage, and if it falls below the reset threshold voltage, it will trigger a reset. It also has a manual reset pin that can be activated by an external signal. Additionally, the PMIC provides a programmable watchdog timer. The watchdog timer will reset the system after a specified time interval. This is useful for the detection and prevention of system lockups.

The APX803S05-40SR-7 also includes two logic output pins, which can be used to indicate reset status and power supply voltage status. The PMIC also includes an interrupt pin, which notifies the system of the power supply voltage status.

In summary, the APX803S05-40SR-7 is a supervisor PMIC from ON Semiconductor. It is used in applications that require low power reset, and it is suitable for industrial, consumer, and automotive applications. The PMIC is highly reliable, with an extended temperature range and high immunity to interference. It has an adjustable reset time window, an adjustable reset threshold voltage, and a programmable watchdog timer. In addition, the PMIC provides two logic output pins and an interrupt pin. The versatility of the APX803S05-40SR-7 makes it an ideal choice for a variety of applications.
