The S-80929CNPF-G8ZTFU is a part of the PMIC - Supervisors family of integrated circuits designed for low power applications. This device is designed for monitoring the battery voltage, input voltage and temperature of an electronic system in order to provide an alert when any parameter is out of range. It is suitable for use in portable electronic systems such as tablets, cell phones, and medical device.

The S-80929CNPF-G8ZTFU is built on a 0.35um process using a CMOS technology, providing a full range of monitoring functions and adjustable reset and threshold switching levels. It consists of a Voltage Supervisory Circuit (VSC), a Temperature Sensor and a Timer circuit. The VSC is the key element of the circuit, providing an effective and reliable way to monitor the input and battery voltages, providing a Reset Out and an Output for enable, interrupt or Cycle-by-cycle control. The reset and threshold levels are highly adjustable and are set on the chip to minimize external components.

The Temperature Sensor is used to monitor the internal temperature of the system, providing an Output when the temperature is lower than a preset threshold, preventing the system from entering an over-temperature condition. It is powered from an external source and requires an input of 4.5V to operate. The Timer circuit is used to provide a Reset Out or Interrupt when the input voltage has gone above or below the threshold set by the user. The Timer circuit is also adjustable, allowing a flexible design.

Apart from the voltage, temperature and timing functions, the S-80929CNPF-G8ZTFU also provides advanced protection features such as overcurrent and undervoltage protection, bypass mode and auto-selectable start-up sequencing. These features ensure the highest levels of protection against any possible external transient or system faults.

The S-80929CNPF-G8ZTFU is ideal for use in a wide range of portable electronic devices, providing advanced monitoring and protection capabilities in a low-power package. Its highly adjustable reset and threshold levels and protection features make it suitable for use in a variety of applications such as smartphones, tablets and other portable electronics.
