The S-80847CNPF-B88TFG integrated circuit, also known as a “supervisor”, is constructed to keep electronic circuitry from suffering from dangerous or damaging problems caused by oversights and suboptimal conditions. More specifically, supervisors provide accurate and long-lasting performance for fail-safe monitoring of critical voltages, current levels, and other conditions related to the operation of the circuit.

The S-80847CNPF-B88TFG part is manufactured by Sanken and listed in the “PMIC - Supervisors” application field category. This supervisor consists of two high precision voltage monitors with power reset, watchdog features. It is suitable as an active reset solution for monitoring power supply voltage and an overvoltage management on embedded systems.

The device is specified to operate with a single input Supply Voltage ranging from 2.6V to 6V and the device\'s operation temperature ranging from -40 to 85 degrees Celsius. It offers a fast and accurate power-on reset for system supervision and the watchdog timer for application timeout monitoring. The power reset is active after the 8ms delay from when the power is connected and the watchdog-timer reset is active after a delay from a low (or high) pulse wide, which is to be set with a single external capacitor.

The S-80847CNPF-B88TFG parts also have a ‘startup lock’ function, a feature that prevents malfunctioning or unexpected resetting if there is a sudden power failure while operating. It also features a low voltage detection circuit with a user selectable reset threshold, adjustable over a range of 1.6V to 6V.

The S-80847CNPF-B88TFG operates according to the principle of detecting any sudden, disturbance-level voltage changes which terminates periodic reset cycles and, in the event of an error, produces an output signal that triggers precise reset conditions. The reset is carried out according to either the power supply On/Off input, or a manual reset, or the watchdog timer. The reset s ignal stays active until power is removed or the error condition is eliminated.

In conclusion, the S-80847CNPF-B88TFG is an ideal device for embedded system applications requiring long-term performance stability, precise power-on reset functionality, and protection for the system design in cases of sudden power changes. Its range of operating conditions ensures reliable performance in a wide variety of applications and its overall design makes it an ideal candidate for use with embedded systems that require properly functioning reset signals and power monitoring.
