Power management IC (PMIC) with advanced reset ICs is rapidly becoming an important component for system designers. Among many, the MAX690SESA+T is a miniature reset and supervisor IC designed for 5V systems. The component provides an automated system reset through its integrated PTC, electronic circuit breaker, Delay Reset, Watchdog Timer and Power-On Reset. Using this integrated circuit reduces the number of external components, and also save space and cost.

The MAX690SESA+T is a versatile, robust and efficient solution for system supervisor applications for products that require high accuracy performance in reset and other safety functions. The component comes with a minimal reset and robust immunity feature which ensures high level of fault protection and reliability.

The MAX690SESA+T is based on the supervisory concept of keeping precise track of system power supply and processor activities externally, and ensure that oscillator frequencies are precisely monitored internally. This achieves a highly reliable and independent reset system. The MAX690SESA+T works independently and automatically issues a reset pulse when the power supply drops, or as determined by user.

The reset pulse is issued in two forms: Low-voltage PTC activation and Delay Reset timer. The LOW-voltage PTC activation generates a maintained low voltage reset signal when the system fails to supply desired voltage levels whereas the Delay Timer reset does the same after a preset delay period. This ensures proper resetting of the system ensuring safety and reliability.

In addition to low-voltage PTC activation, the MAX690SESA+T comes with a wide range of features for increased safety for electronic devices. Its features include power-on reset, electronic circuit breaker and a watchdog timer.

The Power-On Reset feature ensures that the system is reset upon power up or system reset. It functions as a conductor between the external supply and the processor and is active during period of rapid supply fluctuations.

The Electronic Circuit Breaker is a unique feature that isolates an AC or DC supply line to cut off the drain of current in case of an overvoltage or an overcurrent condition. This will help reduce the number of parts used in the system reducing space and cost.

The Watchdog Timer is a vital part of the system which monitors the activities of the processor independently. It is a timer that is reset periodically and when the timer reaches a timeout value, the reset signal is triggered notifying the system to reset.

In conclusion, the MAX690SESA+T is a highly efficient and robust PMIC solution which provides a reliable and independent reset and supervisor system. Its wide range of features ensures system safety, while reducing the number of external components and thus saving space and cost.
