PMIC – Supervisors

PMIC (Power Management Integrated Circuits) supervisors are essential components of power management systems. They provide system level management of power subsystems and other related systems. The APX810S00-44SR-7 is a power supply management integrated circuit (PMIC), also known as a supervisor. It is a high-accuracy voltage monitoring device that monitors power supply conditions in power management systems.

Applications & Uses

The APX810S00-44SR-7 is used mainly for power supply voltage monitoring and system protection in power management systems, such as in electronic devices such as digital audio players, game consoles, and automotive applications. It can detect irregularities or failures in the power supply environment and provide protection to the system. Additionally, it can be used to monitor the battery voltage in battery powered systems, allowing the circuit to reduce system power consumption and prolong the battery life.

The APX810S00-44SR-7 is also used in the protection of non-volatile memories in applications such as automotive ECUs, temperature control systems and smart meters. By monitoring the power supply, it ensures reliable operation of the non-volatile memory and prevents data losses or corruption. Furthermore, it can be used in applications where the power is often unstable, as it can detect and protect against over/undervoltage events.

Features & Benefits

The APX810S00-44SR-7 has a wide operating voltage range from 1.5V to 5.5V. It has a typical accuracy of +/-15mV, allowing for precise voltage monitoring. The output current is adjustable with a maximum of 10mA and a minimum of 15µA, allowing the circuit to be used in a wide range of applications. It also has a low power consumption of 5µA, allowing for efficient system operation. It is housed in a LCC-8 package, making it suitable for a range of applications.

The APX810S00-44SR-7 has a slew-rate control mechanism which allows for fast response and reliable protection. It also has a wide input filter bandwidth which allows for a more accurate voltage monitoring and protection. It has built-in EMI filter, a power-on reset (POR) and power-down reset (PDR) circuits which reduce noise and maintains the internal register status during power transients.

Working Principle

The APX810S00-44SR-7 works by monitoring the voltage level of a power supply using its internal reference voltage circuit. When the voltage is too low or too high, the circuit will shut itself down and reset the system. The output current of the circuit is adjustable, allowing the circuit to be used in different environments. It also has a slew-rate control mechanism which helps to reduce the response time of the circuit and ensures reliable protection. The built-in filter helps to reduce noise and improve the accuracy of the voltage monitoring.

The APX810S00-44SR-7 has a power-on reset (POR) and power-down reset (PDR) circuits which reset the circuit when the power is applied or removed. It also has an EMI filter which reduces the EMI noise and improves the accuracy of the voltage monitoring. Additionally, the circuit has a low power consumption of 5µA, allowing for efficient system operation.
