PMIC - SupervisorsPower Management Integrated Circuits (PMICs) have revolutionized the way electronic systems are developed. The capability of these circuits to control, monitor, and bridge electrical power from a variety of sources to a wide range of consumers has enabled numerous advances in electronic design and architecture. One of the components of these integrated circuits is the supervisor, which plays a key role in embedded systems.The XC6123D433MR-G is an example of a supervisor IC, used primarily in the automotive and industrial markets. It is a medium density, low-voltage, low-power supervisor which provides three configurable reset circuits, four input/outputs, a watchdog timer and a non-maskable interrupt.Reset Circuits:The XC6123D433MR-G has three configurable reset circuits. The primary reset circuit is designed to monitor the power supply and reset the system in case of an power supply undervoltage or overvoltage. The second circuit is a user-programmable timer which monitors the elapsed time since the last reset, and can generate a reset based on a predetermined timeout. The third circuit is the watchdog timer, which can generate a reset in the event of a system lockup or inactivity.Input/OutputsThe XC6123D433MR-G also contains four general purpose input/outputs which can be used for a variety of purposes. For example, the inputs can be used for measuring voltages and currents, or for monitoring the status of external components. The outputs can be used to control external components such as LEDs, switches and relays.Non-Maskable Interrupt (NMI)The XC6123D433MR-G also contains a Non-Maskable Interrupt (NMI) pin which can be used to detect a system crash or other unexpected behavior. The NMI pin can also be used to trigger external logic to take corrective actions in case of an imminent system crash.ConclusionThe XC6123D433MR-G is an extremely versatile supervisor IC, designed for a wide range of applications. Its programmable reset circuits, input/outputs and non-maskable interrupt make it an ideal choice for automotive and industrial applications. Its low-voltage, low-power design makes it an excellent choice for battery-powered systems. Its small footprint and wide operating temperature range make it an excellent choice for embedded system designs.
