The RT9726 is a temperature switch with wide input voltage range. The over-temperature threshold point is generated by a negative temperature coefficient (NTC) thermistor and a setting resistor. The RT9726 provides an active-low, opendrain logic output. OT goes LOW when the NTC pin voltage is lower than 50% of the REF voltage threshold. The RT9726 provides t.
