Power management integrated circuits (PMICs) are devices that regulate and control the charge, flow, storage, and dispersion of electrical energy in computers, telecommunication systems, and other electronic systems. One of the key components of PMICs are supervisors, which monitor the power and performance of the system and respond to changes in the power supply. S-80952CLMC-G7NT2U is one such supervisor, and it is used in a variety of applications to ensure that the power is managed and maintained properly.

The S-80952CLMC-G7NT2U is a single- and dual-rail supervisory circuit, designed for both on-board power rail monitoring and power-on reset generation. It offers both non-volatile and field-updatable functionality for either single or dual power rails, making it a versatile solution for a wide range of applications, including Ethernet switches and routers, optical drives, modems, video cards, and electric vehicle power systems.

The S-80952CLMC-G7NT2U utilizes an advanced voltage and current sense technique to monitor the power rails, with an adjustable resistor to provide programmable input sensitivity. The low-power comparator circuit can provide high input current accuracy, while the low power operation helps to optimize system performance. The integrated circuitry is housed in a tiny 1.2mm x 1.0mm, 8-pin Micro Lead Frame Package (MLF) with an extended temperature range of -40°C to +105°C, making it suitable for use in a wide range of applications.

The S-80952CLMC-G7NT2U’s Dual-rail Power Monitor feature improves accuracy and reliability by monitoring both the high and low side on dual powered rails, providing accurate voltage and current readings for each rail. The Power Good signal generated by the S-80952CLMC-G7NT2U can be used to isolate the circuit from the power rail when a fault is detected, eliminating cross talk and ensuring reliable operation. In addition, the supervisor can detect power rail variability, temperature changes, and other conditions that can affect system performance, and can provide an output signal to indicate the presence of an anomaly.

The S-80952CLMC-G7NT2U also features programmable voltage and current threshold levels, adjustable start-up time, power-on reset delay, and a programmable active-high or active-low reset signal. This flexibility makes the supervisor well-suited for use in applications that require different voltage and current sensing levels, as well as applications that require a reset signal of varying lengths. Furthermore, the supervisor’s low power operation ensures that it won’t interfere with system performance while providing accurate voltage and current readings.

In summary, the S-80952CLMC-G7NT2U is a versatile supervisor that is suitable for a diverse range of applications and offers superior performance and reliability. Its power monitoring and reset generation capabilities make it ideal for use in applications such as routers, modems, video cards, and electric vehicle power systems, providing reliable protection and assured operation.
