PMIC (Power Management Integrated Circuit) supervisors are integrated circuits (ICs) that can help during design, development and implementation of a complete power management IC. In many applications and system designs, the circuity of PMIC supervisors can be used to monitor, control, and detect voltage, temperature and other critical parameters. By combining all of these features, PMIC supervisors can provide high-performance and fault-proof power management for many different applications.

One such PMIC supervisor is the APX810S00-40SR-7. This part is a microprocessor-supervisory circuit particular designed to provide a highly-accurate and reliable voltage and temperature monitoring and control. The part offers +2.7V to +5.5V input voltage range and +3V output voltage range, making it suitable for many industrial, commercial, and consumer applications.

When it comes to its application field, this part can be used in broadly in board-level power sequencing and reset applications. It can be used for providing reset signals for a range of microcontrollers, DSPs, and FPGA as well as other devices. The features of the APX810S00-40SR-7 make it ideal for a wide range of PC motherboard, portable electronics, and other power management products.

The APX810S00-40SR-7 features thermal reset mode and pin function compatibility with other supervisory devices. It offers three monitoring comparators with adjustable thresholds and reporting the active RESET output. This output can be routed to the RTpin, a selectable active-low RESET output or an Interrupt Output pin. These functions can be used to create reliable power-up/down sequence cycles that help minimize the time taken to reinitialize components when a power supply fails.

In terms of its working principle, the APX810S00-40SR-7 operates through a simple three-step process. First, it detects the VCC voltage and compares it to its pre-defined threshold. Second, it measures the temperature and compares to its temperature trip point. Finally, upon detection of the VCC falling below its pre-defined threshold, the APX810S00-40SR-7 asserts its RESET output. In case of a temperature trip, the part generates an active reset.

In addition to its active reset output, the APX810S00-40SR-7 also provides an optional interrupt output. This output can be used to alert the system of any over-voltage or temperature threshold trips. The part can also be configured to provide a power-on reset if enabled via an external resistor-capacitor R/C network. This feature is useful in applications such as power-on reset circuits or a series of power monitoring circuits.

The APX810S00-40SR-7 is a powerful and reliable PMIC supervisor that can be applied in a wide number of applications. It features low quiescent supply current, low voltage and temperature trip points, and adjustable trip points for monitoring. The part is also the ideal solution for creating more reliable power-up/down sequence cycles. All these features make the APX810S00-40SR-7 a great choice for PC motherboard, portable electronics, and other power management products.
