High-Voltage Hysteresis Selectable Temperature Switch

RT9726

Update Alert Share

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, open-drain logic output. OT goes LOW when the NTC pin voltage is lower than 50% of the REF voltage threshold. The RT9726 provides the selectable hysteresis mode that can be set by the EN pin Input voltage. The IC is available in SC-70-6 package.
