S-80835CNPF-B8UTFG

Power Management Integrated Circuits (PMICs) are widely used in both commercial, Industrial and aerospace and military applications. Supervisors are one of the most widely used PMICs, and S-80835CNPF-B8UTFG is an example of such a part. This part is designed to provide control, voltage, output and timer functions.

The S-80835CNPF-B8UTFG\'s applications range from embedded systems, industrial automation and industrial controllers, to radar applications and backup power controllers. Its excellent reliability and long-term stability make it suitable for long-time operating applications. It has low power consumption and can work reliably in extended temperature ranges, both making the S-80835CNPF-B8UTFG an ideal choice for harsh environments.

The S-80835CNPF-B8UTFG is a low-cost and compact single-supply supervisor. It monitors two independent supplies and can also be used for other diagnostic functions. With two independent 0.7V voltage supply monitors and two independent 250ms timer outputs for reset and power-fail detection, the S-80835CNPF-B8UTFG can be used to protect systems against short-term power supply interruptions and overvoltage faults while increasing their efficiency.

The S-80835CNPF-B8UTFG\'s working principle is relatively simple. The two voltage detectors are connected to two separate dedicated supply lines, monitoring both the magnitude and polarity of the supply voltage. If the supply voltage exceeds either the low or high threshold, the S-80835CNPF-B8UTFG will trigger the active-low reset or power-fail outputs, indicating that the fault condition has been detected and that the system must be reset or powered down.

The two timer outputs are also independent and can be used for different purposes. The timer output functions as an auto-reset timeout after a specified time period, triggered by either a low supply voltage or a high supply voltage. In the case of a low voltage, the timer output will remain active for as long as the voltage remains below the low threshold. For a high voltage, the timer output will remain active for a specified duration. This allows the S-80835CNPF-B8UTFG to monitor the supply voltage and reduce the risk of prolonged power-failure or overvoltage fault conditions.

The S-80835CNPF-B8UTFG also offers several other features, including I/O toggle, reset pulse width adjustment, reset generation and polarity control, delay time setting and voltage monitoring thresholds. The toggle output allows the user to select between reset and power-fail mode during normal operation. This feature can also be used to implement power management preferences, as well as provide an easy method to switch between normal and power-fail settings.

Overall, the S-80835CNPF-B8UTFG is a reliable, low-cost single-supply supervisor used for controlling, voltage, output and timer functions in a wide range of environments. With two independent voltage detectors, two timer outputs for reset and power-fail detection, and several additional features, the S-80835CNPF-B8UTFG is capable of reliably monitoring and controlling system voltage for superior protection.
