PMIC - Supervisors : X4645S8I-2.7A Application Field and Working Principle

PMIC or Power Management Integrated Circuits (PMICs) provide an efficient and effective way of managing, controlling and distributing the power requirements of digital electronic circuits. Supervisors are special type of PMICs that are used to monitor power supply voltages and initiate appropriate actions when voltage levels change.

The X4645S8I-2.7A is a Supervisors with proprietary technology, designed to monitor power supply voltages and detect under-voltage conditions. This supervisors implements a 1 millisecond response time for an under-voltage condition. In addition, it offers an adjustable asserted output voltage for a reset threshold. Furthermore, it is configurable for a 4.75V to 5.25V reset threshold range. This supervisors has a power up and power down low-power mode and its supply current is as low as 4µA maximum when enabled.

Application Field of X4645S8I-2.7A Supervisors

The X4645S8I-2.7A Supervisors is widely used in various applications where fast response times and low-power modes are important. It can be used to protect sensitive digital logic, power monitoring equipment and portable electronic devices. This supervisors is suitable for battery management systems, solar panel systems, and other high-power applications. Furthermore, it is ideal for automotive applications due to its low-power operation and fast response time.

Working Principle of X4645S8I-2.7A Supervisors

The X4645S8I-2.7A Supervisors works by monitoring the power supply voltage and detecting under-voltage conditions. When the supply voltage drops below the configured reset threshold, it will activate a reset signal to the devices as protection from the under-voltage. This reset signal can be configured as a low, high, open drain or N-channel type depending on the user’s requirements. The reset signal is active for one millisecond under an under-voltage condition and can be extended by holding it low for longer periods.

The X4645S8I-2.7A Supervisors offers an adjustable voltage range for the reset threshold. It supports a wide range of 4.75V to 5.25V, depending on the user’s requirement. It also offers a low-power mode that is ideal for applications that require low power consumption. Its maximum active power consumption is 2.1mW, and its typical quiescent current is 4µA. Furthermore, this supervisors has an operating temperature range of -55°C to 150°C.

Conclusion

The X4645S8I-2.7A Supervisors is a highly efficient and reliable solution for monitoring power supply levels and detecting under-voltage conditions. It has a quick response time and a wide operating temperature range for various applications. The adjustable reset thresholds and low-power modes make this device ideal for automotive and other high- power applications. This Supervisors is an excellent choice for protection from voltage drops and power supply management.
