The S-80842CNNB-B83T2G is a single-chip supervisor designed for monitoring power issues on the system level. This state-of-the-art microcontroller offers ultimate system-level protection against unpredictable power failure in a wide range of applications. It incorporates integrated circuit technology to monitor microprocessor activity and respond instantly to emergencies. The supervisor is a cost-effective and space-saving way to ensure maximum reliable system operation over the product lifespan.
The S-80842CNNB-B83T2G can be used in a variety of applications including desktop, notebook, and netbook computers, industrial control and automation, servers, gaming machines and other devices that require reliable power management. The device uses advanced integrated circuit technology to monitor the power supply and detect power shortages, surges, and voltage drops. If an emergency exists, the supervisor will respond quickly and take appropriate action to maintain system integrity.
The S-80842CNNB-B83T2G works by sensing an undervoltage condition and triggering an action to restore the power supply. The device contains an analog-to-digital converter for measuring power supply voltage levels and programmable thresholds for undervoltage detect. Contained in an ultra-thin 8-pin package, the supervisor is typically placed near the power source and uses a single, dual- or triple-supply voltage range. Communications between the supervisor and the system logic is done via a serial interface.
The device also incorporates an adjustable reset timeout. When a power outage occurs, the supervisor verifies that the power supply has been restored to normal. Reset timeout is adjustable within predetermined levels so that the system can be held in the reset state for a minimum of 0, 6, 12, 18, 24, 30, 36 and 42 seconds. This prevents the system from restarting too quickly and potentially overloading the power supply.
In addition, the S-80842CNNB-B83T2G features a watchdog timer. This is used to detect any system malfunction that cannot be detected with the undervoltage feature. The watchdog timer is activated and monitored by a user-defined program that can be downloaded to the device. If the specified interval expires, the supervisor will trigger a system reset to return the system to normal operation.
The S-80842CNNB-B83T2G is designed to be a simple and efficient solution for embedded applications requiring reliable power management. With its embedded features, the supervisor is able to provide the highest level of performance and system stability while cutting costs.
