ADM8691ARU

The ADM8691ARU is classified as a Power Management Integrated Circuit (PMIC) Supervisors. It is a dual tracking supervisor that provides a simple, low cost solution for monitoring two power supplies. It helps with system voltage regulation in battery-powered and other computing systems. The ADM8691ARU supervises two voltages (V1 and V2) to provide accurate tracking of either two positive or two negative supplies.

The ADM8691ARU can be used in a wide range of applications such as portable devices, notebook computers, mobile phones, GPS units, wearable technology, digital cameras and point-of-sale systems. It also finds applications in battery management, power indicators, residential and commercial alarm systems, industrial grade equipment, digital thermometers and other home durables.

The main feature of the ADM8691ARU is its high precision tracking of two positive supplies. It uses a differential amplifier circuit to monitor the voltage difference between the two supplies (V1 and V2). The amplifier circuit then converts this voltage difference into a digital measurement. This digital measurement is then fed into the comparator circuit which compares the measurement to the two thresholds (V1+/V1- and V2+/V2-). When the voltage difference between the two supplies crosses either of these thresholds, the output of the comparator circuit changes. This change in output can be used to trigger a reset signal or an alarm.

The ADM8691ARU also features a low supply-current standby mode that can be used to conserve power in battery-powered systems. When the device is operating in the standby mode, it can detect changes that occur between the two supplies (V1 and V2). When the voltage difference between the two supplies crosses either of the preset thresholds, the device automatically switches from standby to active mode. This switch from standby to active mode can be used to feed a reset signal and trigger an alarm if needed.

The ADM8691ARU also features a variety of adjustable parameters that help with system performance. These parameters include the hysteresis settings for the two supplies, the temperature coefficient for the V1 and V2 channels, the response time of the comparator circuit, and the delay time of the RESET output. All of these parameters can be adjusted to provide an optimal system performance that suits the specific application.

Overall, the ADM8691ARU provides a simple and low-cost solution for accurate tracking of two positive supplies, while being able to support a wide range of applications. The device also offers adjustable parameters to help with system performance, and a low supply-current standby mode to conserve power in battery-powered systems.
