Additional Details

The R3111H601C-T1-F has a fixed detection voltage of 6.0V. The open drain output requires a pull-up resistor. The built-in delay circuit prevents spurious resets due to momentary voltage dips. The hysteresis helps to avoid chattering around the threshold voltage. The operating temperature range is a crucial parameter for ensuring proper operation in different environments. The supply current is typically very low, making it suitable for battery-powered applications. Further technical details, including the output voltage, delay time, and operating temperature range can be found in the Ricoh datasheet for the R3111H601C-T1-F.
