A PMIC-Supervisors,DS1814AR-5-U is a programmable,CMOS supervisors device with an integrated watchdog timer and reset buttom. This tiny supervisor has a tiny form factor for a vast range of applications. It is versatile, low power, and cost-effective in many systems–especially in automotive, automotive power,appliance,industrial and consumer applications. DS1814AR-5-U is compatible with a wide variety of voltage rails and includes windowed and push-on reset buttons for fast resetting. Additionally, it has integrated internal on-chip passive components that can support overvoltage protection.

The DS1814AR-5-U supervisor is designed to regulate power supply voltages and detect fault conditions under varying input and load conditions. It will operate in several different voltage rails and is designed to provide an efficient and reliable solution to monitor and protect all of the user’s system power rails. It detectors and protects against various fault conditions including brown-out, overvoltage, undervoltage and over-temperature conditions. Additionally, it has a watchdog timer to detect and protect against system hang-ups. This watchdog timer can be programmed to reset the system if it does not detect activity at the processor for a set period of time.

The DS1814AR-5-U is a low-power, low-voltage supervisor that makes use of several economical, internal passive components to provide overcurrent and overvoltage protection. The supervisor utilizes a single-wire I/O interface, allowing for the connection of multiple DS1814AR-5-U devices in a variety of voltage ranges. The Supervisor has an additional feature that will allow it to power-up when power returns after a power failure.

In addition to the operating modes described above, the DS1814AR-5-U also has selectable thresholds for the monitor inputs. These thresholds include overvoltage, undervoltage,watchdog timer, and power-good. For watchdog timer and power-good, the time delay interval is programmable. The supervisor also has a tri-state logic output that is configurable as an active low logic or Push-to-Reset. This allows the user to reset their system quickly and easily,as well as providing an easy way to verify that the system is functional and running properly.

In addition to these features, the DS1814AR-5-U also has an adjustable power-on reset threshold and hysteresis. This feature allows the user to set the rising and falling reset thresholds, providing more flexibility when managing system power rails. Furthermore, the supervisor can be used in conjunction with external components to detect fault conditions, allowing it to detect faults even after power failures.

Overall, the DS1814AR-5-U supervisor is a versatile, low-power, and cost-effective solution for various system requirements. It is designed to efficiently monitor and protect all of the system’s power rails, detect fault conditions, and reset quickly and easily. It is an ideal solution for automotive, industrial, and consumer applications.
