S-80146BNPF-JG7TFG

PMICs (primary mixed integrated circuits) are used to control a variety of functionality in electronic equipment. PMICs that act as supervisors, also referred to as supervisor ICs, are used to protect equipment from unexpected operating conditions and to maintain optimal operational performance. The S-80146BNPF-JG7TFG is a low power 4-bit Serial Bus Supervisory IC with an adjustable threshold voltage and a watchdog timer. This IC is used in a variety of applications, such as consumer electronics and automotive systems, where protection from accidental malfunctions and catastrophic data loss is key to optimal performance.

The device is designed for low power applications that have tight operating environments. It is configured to detect unexpected signals resulting from bad voltage, floating inputs, over temperature, or current fluctuations that can disrupt system operation. It provides an adjustable reset timer that can be adjusted to respond to set thresholds and can reset the power consumption of the system to its default state if any of these anomalies are detected. It also has advanced features, such as a built-in Watchdog timer that can be used to ensure certain software or hardware elements remain in a certain state or respond to certain instructions.

The S-80146BNPF-JG7TFG features a wide operating temperature range and an on-chip temperature detection circuit. Temperature detection can monitor temperature ranges from -30°C to 125°C, allowing the supervising IC to monitor operating temperatures to detect anomalies. The device also features an adjustable input threshold voltage that can detect changes in the supply voltage from 2.5V to 5.5V.

When using the S-80146BNPF-JG7TFG, the reset signal is initiated when the input voltage exceeds the threshold voltage. This pin is typically connected to an external capacitor that is charged whenever the output of the device goes low. When the voltage across the capacitor exceeds the threshold voltage, the output of the device goes low, which causes the reset signal to be sent. The reset signal is then used to reset the system, reset any variables that may have been affected by the voltage fluctuations, or restart any program or function that is currently running.

The watchdog timer of the S-80146BNPF-JG7TFG is designed to protect the system from unexpected conditions or interference that could disrupt system operation such as a software or hardware malfunction. The watchdog timer has adjustable parameters that determine when the timer will reset the system or, if connected to an external reset circuit, force it to reset. By regularly resetting the system, the watchdog timer ensures system stability and prevents potential malfunctions that can cause catastrophic data loss.

The S-80146BNPF-JG7TFG is an ideal choice for applications requiring low power and advanced protection from sudden changes in the power supply and temperature. It can be used to protect systems from unexpected operating conditions, maintain optimal performance by setting pre-determined thresholds, and protect against data loss using its watchdog timer. This supervising IC is a reliable and easy to use solution for a variety of applications requiring advanced protection.
