PMIC, or Power Management Integrated Circuit, is a family of electronic components existing in modern electronic systems, dedicated to balancing, sequestering and controlling different types of electrical power. In this sense, PM3855DA Supervisors, such as S-80854CLUA-B7FT2G, are not exceptions on their purpose of managing power between different points on an electronic circuit. This device consists of independent functions, regarding voltage levels and power signals, which can be turned on and off individually in order to provide optimal yields for certain applications.

S-80854CLUA-B7FT2G is one of the most popular power management integrated circuits for supervisory applications, due to its simple configuration, wide variety of applications, and superior stability and reliability. This device can be applied on processes that require constant monitoring and control of voltage levels, such as automotive protection systems, over-voltage protection, battery powered systems, industrial equipment, microprocessor-based systems, safety systems, and system reset circuits.

At its core, S-80854CLUA-B7FT2G’s working principle is simple and effective, and it relies on an external voltage reference (VREF) to set an accurate threshold level and power supply (VCC) to power the device. Whenever the input voltage passes the threshold level, a reset signal is generated which, depending on the configuration of the circuit, can reset, disable or keep the monitored circuit in check. In addition, logic-ground-referenced MOS outputs are also available, with various types of packages such as SO-8, SOT-23-6 and MSOP-8.

When it comes to over-voltage protection, S-80854CLUA-B7FT2G provides a tightly-controlled reset threshold, which is set to 95% of VREF. This ensures voltage stability and accuracy, plus improved ESD protection for the circuit. Furthermore, S-80854CLUA-B7FT2G shares common features with other drop-in replacement Supervisors, such as an intrinsic hysteresis of up to 5% and power-fail warning to detect signals near power supply failure, which allows the device to effectively protect the monitored circuit against out-of-control conditions.

Moreover, this PMIC Supervisor offers latch-up protection, allowing the device to avoid short-circuit if a high current flows through the circuit, caused by erroneous signal levels applying to the output pins. In conclusion, S-80854CLUA-B7FT2G is a versatile and straightforward PMIC Supervisor with a wide range of applications, a simple working principle, and reliable protection features.
