RT9726

High-Voltage Hysteresis Selectable Temperature Switch

General Description

Features

^zWide Input Voltage Range : 4.75V to 25V

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 theNTC 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.
