S-80829CLMC-B6OT2U

Power distribution and management integrated circuits (PMICs) are integrated circuits which are used for managing and supplying the power to various circuits and processors of an electronic system. PMICs are specially designed to provide efficient regulation and reduce system level power losses. PMICs are usually divided into different categories based on the functionality: voltage regulators, current regulators, low-dropout regulators (LDOs), DC-DC converters, linear regulators, supervisors and battery chargers, to name a few.The S-80829CLMC-B6OT2U integrated circuit belongs to the Supervisors category of PMICs. The main purpose of Supervisors is to improve the reliability and prevent from failure of the devices by monitoring the output voltages and controlling the reset output pin. These also provide under-voltage/over-voltage protection as well as current limiting and thermal protection. The S-80829CLMC-B6OT2U is is a microprocessor reset circuit that includes power-on reset (POR), system reset, Supervisory reset, and watchdog timer reset.The application field of the S-80829CLMC-B6OT2U mainly includes industrial, automotive, medical and communication systems and is designed to work in harsh environments. It is suitable for monitoring logic voltages and power input/output voltages. Some of the applications include high-end motor control, industrial motor control, battery-operated and Point-of-Load supplies.The working principle of S-80829CLMC-B6OT2U circuit is based on the Supervisory Reset (SR) circuit. The SR circuit monitors the voltage level at the power supply input and the condition of a power-on reset. It ensures that the processor and peripheral circuits are running normally at start-up and during operation. The SR circuit will trigger a reset signal if the supply voltage drops or rises beyond its specified limits, or if a power-on reset signal is not detected. The S-80829CLMC-B6OT2U also features an independently programmable watchdog timer, which can be configured to generate a reset signal in case of an unexpected software reset. The S-80829CLMC-B6OT2U sensor uses a low-power Schmitt trigger circuit to ensure a clean transition between the power on and reset conditions. The watchdog timer has an operating frequency range up to 4MHz. It includes two I/Os to communicate with the host microcontroller: a reset signal, which is output as a low level when triggered, and a signal indicating that the timer has expired. The Watchdog Time can also be programmed to generate a signal when the voltage level passes outside the specified limits.In conclusion, the S-80829CLMC-B6OT2U integrated circuit belongs to the Supervisors category of PMICs and is used for improving system reliability and preventing failures by monitoring output voltages and controlling the reset output pin. It is suitable for applications like industrial, automotive, medical, and communication systems and includes features for under-voltage/over-voltage protection, current limiting and thermal protection. Apart from these, the device is also capable of independently programming the watchdog timer and generating a reset signal upon expiration.
