Power Management Integrated Circuits (PMICs) are ubiquitous in modern day electronic systems and play an essential role in the operation of many devices. They provide power and control the power flow within a system, including voltage regulators, voltage supervisors, power on reset and power sequencing. PMICs can be found in a wide range of applications, from household and automotive electronics to telecommunications, medical and industrial. The S-80158CLPF-JJJTFU is a PMIC supervisor, an integrated circuit which monitors voltage levels, protects circuits from over-voltage and under-voltage, and helps to ensure system reliability.

The S-80158CLPF-JJJTFU is designed to protect digital integrated circuits from voltage and current overload. This is achieved through monitoring the input voltage to determine the acceptable operating range and by creating a reset signal when the voltage is outside the acceptable range. Its low operating current and fast response time make it ideal for applications where power supply voltage is critically important, such as in microprocessors, SRAMs and logic gates.

The S-80158CLPF-JJJTFU is a 3-pin device with a 3.3V operating voltage, an input voltage monitor, and an active low output voltage reset. The input voltage monitor monitors the power supply voltage and generates a reset signal when the input voltage drops below a predetermined voltage level, typically 2.6V. The reset signal is then sent to the integrated circuit being protected. The active low output voltage reset is used to reset the IC after the power supply has stabilized and the input voltage has returned to a safe level. The reset duration is adjustable, allowing the device to be used in applications where the power supply voltage must be held within a certain range for a certain period of time.

In addition to its voltage monitoring capabilities, the S-80158CLPF-JJJTFU also provides over-current protection. This is achieved by monitoring the current draw from the power supply. When the current draw exceeds a predetermined level, the device shuts off the power to the protected IC, preventing it from being damaged by excessive current. The over-current level can be adjusted using an external resistor.

The S-80158CLPF-JJJTFU is an ideal device for protecting sensitive digital integrated circuits from voltage and current overloads. Its active low reset signal and adjustable reset duration ensure reliable operation, and its low operating current and fast response time make it suitable for a wide range of applications. Its simple 3-pin design makes it an easy to use and economical solution for any system where power supply voltage and current must be tightly controlled.
