S-5844A Series www.sii-ic.com TEMPERATURE SWITCH IC (THERMOSTAT IC) Rev.2.3_00 (c) Seiko Instruments Inc., 2011-2013 The S-5844A Series is a temperature switch IC (thermostat IC) which detects the temperature with a temperature accuracy of 2.5C. The output inverts when temperature reaches the detection temperature. The S-5844A Series restores the output voltage when the temperature drops to the level of release temperature. The S-5844A Series operates at the lower power supply voltage of 1.65 V and its current consumption is 0.18 A 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 packages SOT-23-5 and SNT-4A, and the super-small package HSNT-4 (1010).

A V TEMPERATURE SWITCH IC (THERMOSTAT IC) S-5844A Series Rev.2.3_00 Operation The S-5844A Series is a temperature switch IC (thermostat IC) which detects temperature and sends a signal to an external device. The users can select various combinations of the parameters such as the detection temperature, the output form and logic, and hysteresis temperature. Following is about the operation when the DET pin output logic is active "H". After applying the power supply, the S-5844A Series starts to detect the temperature. If the temperature is lower than the detection temperature (+TD), the DET pin output keeps "L". After that, the temperature rises and exceeds the detection temperature, and the DET pin goes in "H". After the detection, the temperature drops and reaches the release temperature (+TD - THYS), the DET pin output returns to "L". Figure 10 is the timing chart. Hysteresis temperature (THYS) Detection temperature (+TD) Release temperature (+TD - THYS) Ambient temperature (Ta) H DET pin output L Figure 10 Operation when the DET Pin Output Logic is Active "H" Seiko Instruments Inc. 11 TEMPERATURE SWITCH IC (THERMOSTAT IC) S-5844A Series Rev.2.3_00 Standard Circuit VDD TEST S-5844A Series DET VSS *1. Resistor (R) is unnecessary for the CMOS output product. Figure 11 Caution The above connection diagram will not guarantee successful operation. Perform thorough evaluation using actual application to set the constant. Precautions * * * * * * * * 12 If power impedance is high, the S-5844A Series may malfunction due to voltage drop caused by feed-through current. Set wire patterns carefully for lower power impedance. Set a capacitor (CIN) of 0.1 F or more between the VDD pin and VSS pin for stabilization. The S-5844A Series may malfunction if the power supply voltage changes suddenly. The S-5844A Series is more easily affected by disturbance or noise if the TEST pin is left open. Set a capacitor (CL) of about 0.1 F for the DET pin to prevent malfunction caused by the noise when the power supply is applied. The S-5844A Series may malfunction if the power supply voltage is lower than the minimum operation voltage. Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit.
