Power management integrated circuits (PMIC) are common components in electronic systems. PMICs provide efficient, reliable, and cost-effective power supply systems by regulating and managing power signals and providing power conversion. Power supply supervisors, also known as system supervisors, are an integral part of a PMIC that are used to control system functionality in the event of short circuit and overcurrent faults, as well as provide information about power supply and system operation.

The S-80129CNMC-JKOT2G is a system supervisor IC with a multi-channel Supervisory IC used to monitor and control system power supplies. It operates as a configurable watch-dog and voltage supervisor, supporting multiple external sensors, such as DSP and microprocessor reset, clock enable and other management tasks. It can also function as an instrumentation amplifier and an adjustable voltage reference.

The S-80129CNMC-JKOT2G is designed for use in applications such as IoT, automotive, industrial, medical and military. The multi-channel configuration provides flexibility for various monitoring and control applications, such as reset and power sequencing. The IC also features an integrated Phase-Locked Loop (PLL) for clock generation and frequency synchronization, as well as a 2-wire serial interface (I2C) for interfacing with host systems.

The S-80129CNMC-JKOT2G system supervisor is capable of monitoring and controlling up to 32 power supplies. It is a highly integrated device with a complete set of features for system supervision, including reset, power-OK, and brown-out detection, event control, power sequencing, voltage regulation and compensation, and start-up and shutdown control. The IC features an advanced architecture that enables the full range of functions to be implemented with minimal components, making it easy to use and cost-efficient.

The S-80129CNMC-JKOT2G system supervisor IC has an adjustable precision voltage reference. This adjustable reference is used to compare the output voltage of the monitored power sources and differentiate between a normal operating voltage and an abnormal condition. When the monitored voltage deviates from preset threshold levels, an event is reported and the supervisor IC will take action to rectify the issue. The S-80129CNMC-JKOT2G also includes a POR (Power On Reset) block and an OR block that are used to control the reset and power sequencing in the system.

The S-80129CNMC-JKOT2G is designed for low power consumption, making it ideal for use in battery-powered systems. The IC operates at a very low supply voltage, as low as 0.9V, and features an integrated charge pump which substantially reduces the total system current consumption. In addition, the IC features a programmable oscillator which can be used to control the frequency of the reset and power sequencing signals, allowing for more efficient power management.

The S-80129CNMC-JKOT2G can be used in a wide range of applications including IoT, automotive, home appliances, consumer, medical, and industrial. It offers many advantages over existing solutions such as reduced component count and cost, improved system performance, and enhanced system reliability.
