X4643S8-2.7

PMIC - Supervisors are essential components that are used to regulate and manage the electrical energy system of an electronic device. The X4643S8-2.7 is a high-performance, low-cost supervisor IC for alternating current (AC) applications. It is designed to manage, protect and monitor the power system and provide considerable protection from overvoltages and overcurrents, as well as many other system failures.

The X4643S8-2.7 works by detecting and controlling the input current or voltage levels in order to ensure that the voltages and currents remain within the safe and efficient range for the particular device or circuit. It helps to prevent damage or malfunctioning of the device due to excessive or wrong levels. Furthermore, the X4643S8-2.7 additionally provides a reset signal whenever the voltage or current levels cross the threshold level. This helps to reset the device in case of potential system failures.

The X4643S8-2.7 provides an integrated short-circuit current limiting and power-on reset circuit that are useful in protecting the device from surges and spikes. Due to its excellent performance and expansive features, the X4643S8-2.7 is ideally suited for a wide range of applications including personal computers, laptop chargers, LED lighting, battery chargers, PDAs, portable media players, smartphones and various AC/DC power systems. It is further well-suited for system that are prone to high-current electrical power such as off-grid and residential solar PV systems.

This device also comes in a very small package size of 2.4mm x 3mm, making it one of the smallest offerings for PMIC supervisors in the industry. It also features industrial grade temperature range of -40°C to +85°C and low operating supply voltage of 2.7V- 5.5V. It is further a low-power device having an operating power consumption of below 100uA permitting use in battery-operated devices.

In addition, the X4643S8-2.7 provides a single-key reset low power timer. This is a useful feature that allows the timer to be adjusted in order to set the time when a threshold is exceeded, allowing the timer period to be paired with the needs of the specific application. This means that the timer can be used to reset the device after a given amount of time, particularly useful in applications that require the device to reset itself without user intervention.

The X4643S8-2.7 also provides a built-in watchdog timer, which helps to detect possible faults or failure in the system and automatically reset the device. The watchdog timers come in a variety of timeout periods, such as 1mS, 2mS, 4mS and 8mS in order to fit the specific needs of the application. This pertains to both the undervoltage and overvoltage protection built into the device.

The X4643S8-2.7 offers a complete solution to electronic device power management. It comes with a wide range of features that make it ideal for a variety of applications, including providing robust and reliable protection to the device. Its small size makes it perfect for devices that require a low profile. Additionally its low power operation makes it useful in battery-operated applications. Finally, its configurable timer and reset features make it a popular choice for many applications that require non-invasive power management solutions.
