Max6823VUK+ is a three-terminal voltage supervisor that provides reset functionality to protect circuits against abnormal operations. As a dedicated supervisor device, it belongs to a category of PMIC- Supervisors that are used to monitor the voltage signals at different points in a system. It is designed to detect undervoltage and overvoltage for two independent circuits and provide reset control for them. It also provides a high active-low reset output, an open-drain reset output and reset filter circuits, making it a suitable choice for applications that require flexible reset control.
Unlike other similar PMIC- Supervisors, the Max6823VUK+ is optimized for low power consumption, making it a good choice for battery-operated or portable systems. It features very low quiescent current compared to conventional solutions and can detect input voltages as low as 0.8V with a maximum voltage of 3.6V.
The Max6823VUK+ is designed with circuitry to reject transient input voltage glitches, spikes and short-term power interruptions, so it is suitable for applications in which home/ office appliances have to cope with sudden and unexpected power outages. It also has a reset filter capacitance so that your system can restore operation within a stable time even after a long period of inactivity.
The Max6823VUK+ consists of a voltage supervisor circuit, reset control logic, and reset output structure. The voltage supervisor constantly monitors the voltage of two independent voltage outputs from the system. When one of the inputs falls below a preset voltage (undervoltage), or rises above a preset voltage (overvoltage), the supervisor output changes from its inactive state to an active state.
The reset control logic within the Max6823VUK+ provides protection for the two independent voltage inputs described earlier, and can also be adjusted for specific voltage levels depending on the application. When both inputs go through a preset threshold, the reset output is engaged and sends a pulse, while resetting the logic circuit.
The reset output, which is an open-drain output, is designed so that it can be driven in either active (high) or inactive states (low). It can be connected to the interrupt pin of a microcontroller, an I/O port of a microcontroller, or other reset devices in the system, to trigger a reset signal when required. The reset output also features a reset filter circuit such that the outputs are not tampered with in the event of any current noise from the system.
The Max6823VUK+ is designed to be small and compact, making it a good choice for space-constrained applications. It is also designed to be rugged and reliable in operation, granting it a long lifespan and low maintenance costs throughout its use. Moreover, its wide supply voltage range of 1.8V-3.6V makes it universal for home/ office appliances, automotive, industrial, and medical applications.
In conclusion, the Max6823VUK+ is a small yet powerful voltage supervisor designed to protect and control circuits in a wide range of applications. Its low power consumption, reset filter circuits, protection against input voltage glitches, and universal voltage range make it a popular choice for applications that require robust and reliable reset control.
