Rev.1.3_00 TEMPERATURE SWITCH IC S-5841 Series The S-5841 Series is a temperature switch IC which detects the temperature with a temperature accuracy of ±2.5°C. This IC restores the output voltage when the temperature drops to the level of release temperature. The S-5841 operates at the lower power supply voltage of 2.2 V and its current consumption is 10 µA Typ. due to CMOS configuration. A temperature sensor with the negative temperature coefficient, a reference voltage generation circuit and a comparator are integrated on one chip, and enclosed into the small packages SNT-6A and SOT-23-5.

Various combinations of the parameters such as the detection temperature, output form and output logic can be selected. The following explains the case when DET output is assumed to be active high and CMOS output. After applying the power supply, the IC starts to detect the temperature. If it is lower than the detection temperature (+TD), the DET pin keeps its status in low level. The temperature rises and exceeds the detection temperature, the DET pin becomes high level. After the detection, the temperature drops and reaches the release temperature (+TD−THYS), the DET pin returns to low level. Figure 8 is the timing chart. Hysteresis temperature (THYS) Ambient temperature (T) Detection temperature (+TD) Release temperature (+TD−THYS) VDD Output from the DET pin VSS Figure 8 Operation when the output from DET pin is active high [Hysteresis setting] In the S-5841 with SNT-6A package, The hysteresis temperature can be switched in 0°C, 2°C , 4°C, 10°C, and is set by the HYS1 pin and HYS2 pin. In the S-5841 with SOT-23-5 package, the hysteresis temperature can be set by the HYS1 pin. By option, the hysteresis temperature of the product is selectable in 2°C and 10°C / 4°C and 10°C.

The followings are about the action when DET output is in active high. If the temperature is lower than the detection temperature (+TD), the DET pin is in low level. Although the output from the comparator goes in active due to noise, if the period in which this status continues is shorter than delay time for noise cancellation, the DET pin keeps its setting low level. After that, the output from the comparator goes in active because the temperature rises and exceeds the detection temperature, so that the period exceeds more than delay time for noise cancellation, the DET pin is set in high level.

Figure 9 Application circuit Caution The above connection diagram will not guarantee successful operation. Perform thorough evaluation using actual application to set the constant. Precautions • • • • • • • Set a capacitor (CIN) of about 0.1 µF between the VDD and VSS pin for stabilization. Set a capacitor (CL) of about 1 µF for the DET pin to prevent malfunction caused by the noise when the power supply is applied. The IC may oscillate by setting a capacitor to the RT pin. Set the RT pin open in use. If the RT pin is short-circuited to VSS, the DET pin becomes active in this IC. Fix the HYS1 pin and the HYS2 pin VDD or VSS in use. Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit.
