The XC61FN2442MRN is a voltage detector IC manufactured by Torex Semiconductor Ltd. This device is designed to monitor voltage levels in electronic circuits and provide a reset signal when the voltage drops below a specified threshold. This particular model has a detection voltage of 2.44V, making it suitable for a range of applications operating at or near that voltage. The device is housed in a small SOT-25 package, which is advantageous for space-constrained designs.

Additional Details

The XC61FN2442MRN uses an internal voltage reference and comparator to accurately detect the input voltage. The open drain output necessitates an external pull-up resistor. The hysteresis feature prevents the output from toggling rapidly when the input voltage is near the threshold level. This device provides a reliable and cost-effective solution for voltage detection and system reset functions.
