Power management integrated circuits, or PMICs, are electrical components that regulate the operational power levels of a device or system. PMICs ensure that individual system modules use only the energy required to perform their tasks while keeping the voltage and current within specified levels. One example of a PMIC is the X5169V14-2.7T1, a supervisor component designed for simple voltage sequencing applications.

The purpose of the X5169V14-2.7T1 is to monitor the power supply of a system and provide an active-low reset output when an overvoltage or undervoltage condition occurs. It also provides an active-low reset output for system wakeup when the supply voltage drops below a programmed threshold. The component is suitable for a wide variety of power supplies, from battery-powered devices to AC-DC power supplies.

The X5169V14-2.7T1 is able to detect power on and power off conditions as well as output low and high status signals. It works across a wide input voltage range of 2.7 to 5.5V, making it suitable for many applications. On the output side, the component provides a reset signal, an open-drain output, and a power-good input. In addition to reset functions, the component can also be used to monitor the power supply voltage and provide an indication when a voltage drop or overshoot occurs.

In terms of specific applications, the X5169V14-2.7T1 is designed for use in consumer electronics products, automotive systems, and industrial machinery. Its ability to detect overvoltage and undervoltage conditions makes it useful for monitoring power supplies in these systems and providing a reset output when the supply voltage reaches a predetermined limit. The component can also trigger a reset output when the power supply voltage drops below a preprogrammed threshold, which is useful for waking up a dormant system.

At a functional level, the X5169V14-2.7T1 incorporates two separate supervisors, each with its own power supply input and reset output. The two supervisors are connected in parallel with each other, meaning they both respond to the same power on and power off conditions. The component has a hysteresis voltage of 200mV, ensuring an accurate reset threshold and ensuring that the voltage stays within normal parameters.

In addition to its supervisors, the X5169V14-2.7T1 also includes an internal voltage reference that sets the reset threshold. The reference voltage is typically set at 2.78V, though it can be adjusted depending on the application. When the input voltage drops below the reference voltage, the reset output will be triggered. When the voltage reaches the reference voltage again, the reset output will be released.

The X5169V14-2.7T1 is designed for operation in extreme temperature environments, from -40 to 85 degrees Celsius. It also has an active low reset output, meaning that it produces a logic low output when the power supply voltage exceeds the reference voltage. In addition, the component is RoHS compliant and UL certified, meaning it meets all applicable safety standards.

To summarize, the X5169V14-2.7T1 is a PMIC that serves as a supervisor for power supply sequences in consumer electronics, automotive systems, and industrial machinery. With a wide operating voltage range, support for extreme temperatures, and UL certification, the component provides a reliable and robust power management solution. Its ability to detect power on/off conditions as well as output low and high status signals, as well as its two-channel voltage operation capabilities, makes it suitable for a wide array of applications.
