PMIC (Power Management Integrated Circuit) is a comprehensive power management solution that integrates several power management blocks into a single chip package. Supervisory circuits are one of the important components in power management systems. The S-80958CLMC-G7UT2U is a supervisor device with integrated current-source, 3-state logic output, 1.0A of source current, up to 3.2V voltage rating, and multiple protection features.

The S-80958CLMC-G7UT2U can be applied in applications including PC, server, VRM/VRM12.0, embedded systems, and DC/DC converters. It is designed for system-level voltage or temperature monitoring, digital sequencing and sequencing, low-voltage detection, brown-out reset, watchdog timer, circuit breaker, MOSFET and diode open drain restoration, and digital systems reset control. It is also suitable for voltage and temperature protection, interrupt, circuit protection, and regulation of low-voltage and temperature critical components.

The working principle of the S-80958CLMC-G7UT2U is that it monitors and measures an input voltage (VIN) relative to a reference voltage (VREF), and sends out a logic signal whenever VIN becomes lower than or higher than the preset thresholds. This signal is used to indicate that a high or low voltage event has occurred and trigger appropriate actions from the system.

The S-80958CLMC-G7UT2U features an adjustable high and low voltage detection threshold, as well as hysteresis voltage and output current. The hysteresis voltage sets the window between the high and low detection thresholds while the output current sets the current sinking ability of the device. Additionally, the device also provides an output delay, which is an adjustable time between the rising edges of VREF and the output monitor transistor, allowing the user to adjust the timing of the output monitor transistor.

In addition to its high-current source output, the S-80958CLMC-G7UT2U also integrates logic outputs and multiple protection features. The logic output is available in 3-state logic to support both high and low level detections. The device also integrates a power input protection circuit, thermal-shutdown circuit, clock-synchronization circuit, and gate-level drive regeneration, providing protection for the power components and preventing system failure.

In conclusion, the S-80958CLMC-G7UT2U is a supervisor device that is suitable for system-level voltage or temperature monitoring, digital sequencing and sequencing, low-voltage detection, brown-out reset, watchdog timer, circuit breaker, MOSFET and diode open drain restoration, and digital systems reset control. It is an effective solution for providing protection to power components and systems. It integrates high-current source output, adjustable high and low voltage detection thresholds, hysteresis voltage and output current, output delay, logic outputs, and multiple protection features.
