The APX810S-44SR-7 is an ultra-low quiescent current supervisor designed for Power Management Integrated Circuit (PMIC) applications. It is suitable for a wide range of systems requiring stabilized outputs with high accuracy, fast response time, and low standby current. This device provides a very low quiescent current solution for a wide range of PMIC applications, including TDMA and GSM systems.

It features a wide operating range from 1.8 to 5.5 V and tolerance down to 0.1%. It has a fast response time of 40 ms as well as a low current consumption of 1 μA in standby. The APX810S-44SR-7 has a wide input voltage range and a fixed delay parameter, making it ideal for low-voltage supply systems. It also provides monitoring of both input voltage and output current.

The APX810S-44SR-7 has an integrated delay timer, which provides a fixed delay time that is adjusted to the need of the application. It also includes enable and reset pins, which enable and reset the device, respectively. The enable pin is active-low, meaning it can be driven low to enable the APX810S-44SR-7, allowing the supervisor to regulate the output voltage. The reset pin is active-high, meaning it can be driven high to reset the APX810S-44SR-7 and disable it.

APX810S-44SR-7 works on the principle of monitoring and controlling the output voltage and current of a system to ensure proper operation and stability. It compares the voltage of the system to a predetermined threshold and if the voltage exceeds this threshold, it sends a signal to the system to reduce the output voltage and current. This reduces the voltage and current in the system, preventing it from becoming overloaded and providing a stable supply. Similarly, if the voltage is too low, the APX810S-44SR-7 will increase the output voltage and current to bring it back to the desired level.

The APX810S-44SR-7 is ideal for applications where output voltage and current must be monitored and controlled, such as in smartphones, PCs, and embedded systems. It provides reliable protection and monitoring of the system, helping to ensure the system runs at a stable voltage. The APX810S-44SR-7 is also suitable for applications using low-voltage supplies, due to its wide operating range and adjustable delay parameter.

In summary, the APX810S-44SR-7 is an ideal solution for power supervisors in PMIC applications. It provides fast response time, low standby current and tight tolerances, while also providing reliable control of output voltage and current. The integrated delay timer and enable/reset pins makes it suitable for low-voltage supply systems, ensuring the device is able to adjust to the specific application needs. The APX810S-44SR-7 is an essential component for any power supervisor in a PMIC application.
