Additional Details

The S-81235AG-RI-T1 offers a cost-effective solution for voltage monitoring and reset generation. The '35' in the part number suggests a 3.5V detection threshold. The hysteresis feature prevents unwanted reset signals caused by minor voltage fluctuations. The open-drain output provides flexibility in interfacing with different logic levels. The small package size allows for easy integration into space-constrained applications. To obtain precise specifications, including detection voltage accuracy, release voltage, operating temperature range, and pinout information, consult the device's datasheet. This voltage detector is particularly useful in systems where a reliable power-on reset or voltage supervisor function is required to safeguard against data corruption or system instability caused by undervoltage conditions.
