S-80139BNPF-JGYTFU

The S-80139BNPF-JGYTFU is a voltage supervisor IC designed to monitor one or more power supplies, and provide stable power supply as needed. It monitors and maintains the output voltage at its set level, and provides protection against over-voltage conditions and over-current conditions. It can also be used to reset any digital logic circuits, providing a hard-reset to reset all logic circuits.

The device is manufactured using advanced CMOS process for low power consumption, and the output voltage and threshold are set through external resistors. The output is an open drain connection, allowing for an active low reset output. This can be connected to the circuit’s reset line, or to an external reset button.

The device also has an active high output, which is used to indicate the battery voltage is out of the expected range and requires reset. The active high register can be connected to an external interrupt or a timer to provide a reset.

The S-80139BNPF-JGYTFU has various applications, ranging from resetting digital logic circuits and microcontrollers, to providing power supply to circuits operating in noisy environments. It can also be used in power surge protection, low-voltage monitoring, and over-temperature protection.

The working principle of the S-80139BNPF-JGYTFU is fairly simple. It utilizes a voltage comparator, in which one input is the reference voltage, and the other is the voltage from the circuit. If the voltage from the circuit exceeds the reference voltage, then the output is triggered, providing either an active low or an active high signal.

In addition, the S-80139BNPF-JGYTFU is equipped with glitch detectors, which are used to detect sharp peaks in current that can occur when power supplies are switched on or off. These glitches can cause complex systems to malfunction, and the S-80139BNPF-JGYTFU has built-in protection against them.

Overall, the S-80139BNPF-JGYTFU is a highly reliable voltage supervisor IC, designed to provide stable power supply, and protection against over-voltage and over-current conditions. Its applications range from protecting digital logic circuits and microcontrollers, to providing power supply to circuits operating in noisy environments. Its working principle is simple and effective, and its glitch detectors provide protection against sudden power supply changes.
