X5165S8Z-4.5A

Power Management Integrated Circuit (PMIC) - Supervisors are integrated circuits used to control and regulate power resulting from the power supply in devices. Such devices typically require a noisy AC power supply on a cold start, which is regulated to a low voltage supply in order to operate. One such product is the X5165S8Z-4.5A, which provides voltage and current monitoring and regulation, as well as short circuit protection.

Overview of the X5165S8Z-4.5A

The X5165S8Z-4.5A is a negative and positive supply supervisor that operates with a power supply of 4.5V. It is designed for robust operation and features a wide input voltage range of 2.5V to 5.5V. The X5165S8Z-4.5A includes both pre-biased detection and extended reset time-outs, as well as a signal output that indicates a power-on reset or a power-off reset. The chip includes an output driver that takes a minimum of 36 mA and 25 mA for the reset and power-good outputs, respectively.

Application Fields for the X5165S8Z-4.5A

The X5165S8Z-4.5A was designed for various applications, including energy-saving, mobile, and environment control devices. Its adjustable reset delay time-out, adjustable watchdog timer and latch, as well as its suitability for both positive and negative supplies, make it ideal for a variety of applications. Its wide input voltage range and its low quiescent current makes it suitable for battery powered applications.

The X5165S8Z-4.5A has a number of features that may be useful in a variety of environments, ranging from industrial applications to consumer electronics. It is low cost and low power, allowing it to be used in battery-powered applications. Additionally, it can be used in an array of applications such as automated vehicular systems, industrial, and medical. The X5165S8Z-4.5A also has the ability to withstand transients and short-term disturbances.

The Working Principle of the X5165S8Z-4.5A

The X5165S8Z-4.5A monitors both positive and negative power supplies, providing power-off and power-on reset signals when voltages go above or below predetermined thresholds. The chip is powered on and off using separate external power good signals. Once powered up, the chip will send out a preset reset signal when the voltage supply has passed its threshold. The reset signal can be routed to other systems as long as the reset requirements are met by the chip.

The X5165S8Z-4.5A also includes an adjustable power-on delay time which ensures reliable operation when there is an unstable or noisy power supply. The chip also supports adjustable watchdog timers with either a window or a single-timeout feature. Watchdog timer settings can be adjusted by a programmed resistor, and the single-timeout feature can be used to detect stuck signals or incorrect processing.

The X5165S8Z-4.5A provides additional flexibility with adjustable reset output levels that make it suitable for various applications. In addition, the chip has a built-in reset output driver that can be powered with both positive and negative supplies, allowing it to be used in a variety of applications. The low quiescent current gives it longer battery life and the ability to operate over the temperature range of -40 to 125 degrees Celsius.

Conclusion

The X5165S8Z-4.5A supervisor provides an adjustable power supply management integrated circuit for a variety of applications. The adjustable reset delay allows the chip to handle unstable power supplies, while the adjustable watchdog timer makes the chip suitable for multiple applications. With a wide input voltage range and the ability to operate over a wide temperature range, the X5165S8Z-4.5A provides robust protection and monitoring for today\'s devices.
