ADM8616RCYAKSZ-RL7 is a voltage supervisor for integration into low-power-consumption systems and is classified as a PMIC (power management integrated circuit) - Supervisors.

The device provides a precise and reliable method of monitoring one voltage, regardless of fluctuations in power or variations in temperature. It also allows for a reset pulse to be generated for reset signal input.

ADM8616RCYAKSZ-RL7 is used in many applications, including low-power embedded applications, personal computers, and networking applications as well as mobile and consumer applications. The device is particularly suited to battery-driven applications, as it has a low power consumption of only 1.3 μA.

The supervisor provides a regulated output voltage of 1.2V and can be programmed to trip between 1.052V and 1.49V. It also has a hysteresis range of 0.2V and 0.9V and a trip time of 62μs. It is designed to initiate a reset signal, as well as reduce risk of system start-up failure, lock-up or communication errors associated with Brown-out or noise-induced reset.

The active low reset signal is generated by the device\'s internal comparator (which is pre-programmed by the manufacturer)when the voltage falls below or rises above the trip voltage. The reset signal is then asynchronous to the input control voltage. The reset signal does not occur until the input voltage exceeds the pre-programmed trip voltage and a time delay of 62μs.

The supervisor provides a TTL compatible open-drain output to minimize the power consumption of the system. The outputs are active low and the device runs off 5V and 3V. The device can also be configured to operate from unregulated supplies like USB or battery sources.

A fault upper threshold (FUTH) and a fault lower threshold (FLTH) can also be added for counting purposes. FUTH is a higher voltage level than the trip voltage, and FLTH is a lower voltage level than the trip voltage. These additional features allow for monitoring of noisy and/or decreasing power levels.

In addition, the device is temperature compensated to allow for an operating range from -40°C to +85°C. It also has a ‘power-good’ indicator, indicating the presence of the monitored voltage. Furthermore, the device has an enable input and a power enable input which can be used to turn the device off.

In short, ADM8616RCYAKSZ-RL7 is an efficient voltage supervisor used in low-power-consumption applications. It is well suited to battery-oriented applications due to its low power consumption and temperature compensated design. It can also be used to monitor noisy and/or decreasing power levels, as well as provide a ‘power-good’ indicator and reset signals when the input voltage exceeds the pre-programmed trip voltage.
