PMIC - Supervisors are often used in the design of a system to provide power source monitoring and protection. The application field and working principle of the TPS3896ADRYR is a perfect example of how PMIC - Supervisors work to make electronics functions more reliable and efficient. The TPS3896ADRYR is a low-power, high-accuracy voltage supervisor for applications requiring best-in-class power on reset (POR) accuracy.

This device is designed to monitor multiple supplies for system power sequencing and reset applications. It is available in fixed and adjustable reset thresholds in order to accommodate a range of systems and provide reset protection for a variety of voltage conditions. It offers a wide range of reset inaccuracy from 0.15% to 1% depending on the input voltage, output current, and temperature.

The TPS3896ADRYR also features a watchdog timer (WDT) that is factory-programmed to generate a reset signal if the monitored voltage is not within the programmed threshold after a certain duration. The WDT can be used to reset the system if a malfunction is detected, or if the power supply voltage is outside of the specified voltage range. The WDT timeout period is adjustable up to 120 seconds.

The TPS3896ADRYR also provides anOn/Off input pin that can be used to manually trigger a reset signal. This pin can be connected to a push button, allowing a user to manually reset the system. This feature is especially useful when debugging a system or if the voltage goes outside of the normal operating range.

The TPS3896ADRYR also offers an optional leakage current feature that monitors the current across the supply pin. If the leakage current is outside the programmed threshold, the device will generate a reset signal. This feature ensures that no voltage is dissipated unnecessary from an over-current draw, thus protecting other components from damage.

The TPS3896ADRYR is typically used in systems requiring great accuracy and power source stability. Some of the most common applications include microprocessors, digital signal processors (DSPs), analog-to-digital converters (ADCs), solid-state storage devices, memory chips, and other sensor devices that require power stability and accuracy. This device is also well-suited for automotive, medical, and industrial applications that require high-accuracy voltage supervision.

In conclusion, the TPS3896ADRYR is a voltage supervisor that can be used to monitor multiple supplies, provide reset protection and system power sequencing, and ensure power stability and accuracy for a variety of applications. This device is an excellent choice for any system requiring precise monitoring and protection.
