PMIC, or Power Management ICs are essential components in any electronic device. The ADM812TARTZ-REEL7 is one such example. It is a power-on reset and supervisor IC, which is important in maintaining system stability and accurate system functioning.

Applications

The ADM812TARTZ-REEL7 supervisor is designed for use in battery operated, portable applications, where system reset and reset counters are required under low voltage conditions. The IC offers an adjustable supply voltage range from 0.9V to 10V and a precision reference to detect and provide a reset signal to ensure accurate operation in low power state conditions. The device is also suitable for resetting processors, FPGAs, ASICs and multichip modules in harsh environments. It also includes an on-chip comparator with programmable thresholds and is provided with an open-drain analog output.

The IC is also designed for use in a wide variety of applications, including automotive applications, industrial control systems and industrial automation systems. It is also suitable for use in medical devices and instrumentation systems. Other uses include motor control, aerospace and aircraft systems, communication systems, energy systems, embedded system and robotic applications.

Working Principle

The ADM812TARTZ-REEL7 is a power-on reset and supervisor IC which features a precision reference for resetting the target processor when the supply voltage drops below a programmed voltage (VPOR). The IC also features a programmable reset timeout (MRT) period. During MRT, if the supply voltage is within the reset window, the voltage detector continuously monitors and refreshes the reset signal while the reset timeout period is active. When the supply voltage reaches VDD and remains there for the duration of the reset timeout period, the reset signal is removed.

The IC also provides an open-drain analog output which can be used to monitor the supply voltage in real-time. The device also includes an on-chip comparator which utilizes two independent, adjustable voltage thresholds to detect trip points. The comparator can generate an active reset signal if the programmed trip points are not met. In addition, the IC also features an ESD protection to prevent over-voltage and over-current conditions.

The ADM812TARTZ-REEL7 can be used for a wide variety of applications, such as embedded systems, automotive applications, industrial control systems, medical devices, and many more. It is designed to provide a reliable power-on reset and supervisor function for low voltage conditions, ensuring accuracy and robust operation in harsh environments.
