APX810S05-44SA-7

APX810S05-44SA-7 is a supervisor integrated circuit (IC) specific for the power management application, known as PMIC. This chip is designed to supervise the voltage of the power supply, ensuring it is within the values of the revised level. This chip also offers a protection feature, producing a reset output when microprocessor (MCU) becomes non-functional due to extremely high or low power supply voltage or excessive current consumption.

The APX810S05-44SA-7 IC is a highly-reliable power management chip which can operate in different operating voltages for different applications. Typically, this PMIC is used for core voltage monitoring and power sequencing. It has an adjustable limit voltage, up to 5.5V, making it ideal for monitoring core voltage which usually range between 0.5V and 3.3V. In addition, it can also generate reset output and provide auto power-on reset.

The design of the APX810S05-44SA-7 IC consists of four main components: the power up circuit, the monitor circuit, the reset circuit, and the latch circuit. The power-up circuit is responsible for creating a voltage regulated output. It is usually connected to the system\'s power supply so that it can detect and control the voltage fluctuations. The monitor circuit contains an external voltage divider which measures the voltage of the system. The output of the divider is then compared to an internal reference voltage and when the measured voltage reaches a certain value the reset circuit is triggered. The reset circuit then produces a reset output which is latched by the latch circuit. The latch circuit also places the whole chip into a reset state which prevents the chip from generating false reset signals.

The APX810S05-44SA-7 IC is mainly used in embedded applications including computers and microcontrollers, where power management is critical. Additionally, this chip is also found in various applications such as telecommunications, servers, routers, switches, digital cameras, and automotive electronics. Due to its low power consumption, small size, and adjustable limit voltage, the APX810S05-44SA-7 IC is a highly reliable solution for many power management needs.
