Power management integrated circuits (PMICs) are a family of electronic circuits or devices used to manage the various sources of power in an integrated circuit (IC) device. Supervisors, which are a type of PMIC, are responsible for monitoring the input voltages and responding to changes to provide the necessary safety shutdown, power-up sequencing, voltage/current monitoring, and other power management functions required by the system. The S-80960CNMC-G9WT2U is a specific type of supervisor from Renesas Electronics that is used to monitor and stabilize an input voltage for an integrated circuit (IC) device.

The S-80960CNMC-G9WT2U supervisor is designed for single-cell Li-ion battery-powered systems that require accurate input voltage monitoring. It is commonly used in cell phones, personal digital assistants (PDAs), and other handheld electronic devices that include multiple voltage levels and require low power consumption. The device has been designed to monitor input voltages from 1.7V–5.5V, and can be used to detect the state of a single cell Li-ion battery, allowing for accurate control in managing the system\'s power. The device also has several other power management functions such as reset, clock speed control, and power-down detection.

The S-80960CNMC-G9WT2U supervisor is equipped with a built-in alarm and reset circuit that monitors the input voltage and responds in the event of an overvoltage or undervoltage condition. The alarm and reset circuit is composed of an input voltage detector and a reset circuit. The input voltage detector can be configured to detect either an overvoltage or undervoltage condition, allowing the device to trigger an alarm signal and/or reset in the event of an input voltage being outside of the desired range. The reset circuit is designed to be used to reset the system in the event of a fault condition.

The S-80960CNMC-G9WT2U supervisor is also equipped with an adjustable comparator that is used to compare the input voltage to an externally-set internal reference voltage. This comparator is configured to detect overvoltage and undervoltage conditions and can be adjusted to set the desired voltage target at which the system will be reset or triggered to perform an action. The comparator also has a hysteresis function that can be used to adjust the response time for the reset signal.

In addition to the alarm and reset circuit, the S-80960CNMC-G9WT2U supervisor also has power-down detection function that can detect when the system enters a low-power condition. This power-down detection circuit is composed of two comparators that are triggered when a predetermined input voltage level is reached and a reset circuit to reset the system. The power-down detection circuit can be used to automatically switch the system off, or to trigger a power-down sequence to reduce the amount of power being consumed by the system.

The clock speed control of the S-80960CNMC-G9WT2U supervisor is also adjustable. This clock speed control circuit allows for the system to adjust its clock frequency when the voltage levels change, thus reducing the amount of power consumed by the system. The clock speed control circuit is composed of a voltage mode detector and a clock control circuit. The voltage mode detector is responsible for detecting the input voltage level and triggering the clock control circuit to adjust the clock frequency accordingly.

The S-80960CNMC-G9WT2U supervisor can be used in a wide variety of single-cell Li-ion battery-powered applications, from cell phones and PDAs to other consumer electronics devices. The integrated voltage monitoring, alarm and reset, power-down detection, and clock speed control capabilities make this device a viable choice for any system requiring accurate input voltage management. This supervisor is designed to provide reliable and accurate monitoring and power management of an input voltage, ensuring the safety and efficiency of a single-cell Li-ion battery-powered system.
