S-5844A Series www.sii-ic.com © Seiko Instruments Inc., 2011-2014 TEMPERATURE SWITCH IC (THERMOSTAT IC) Rev.2.6_00 The S-5844A Series is a temperature switch IC (thermostat IC) which detects the temperature with a temperature accuracy of ±2.5°C. 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.

S-5844A Series www.sii-ic.com © Seiko Instruments Inc., 2011-2014 TEMPERATURE SWITCH IC (THERMOSTAT IC) Rev.2.6_00 The S-5844A Series is a temperature switch IC (thermostat IC) which detects the temperature with a temperature accuracy of ±2.5°C. 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 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 packages SOT-23-5 and SNT-4A, and the super-small package HSNT-4 (1010).  Features • Detection temperature: TDET = +50°C to +100°C, +5°C step, detection accuracy: ±2.5°C • Low voltage operation: VDD = 1.65 V min. • Low current consumption: IDD = 0.18 μA typ. (Ta = +25°C) • Hysteresis temperature: selectable in 5°C, 10°C, 15°C or 20°C • Selectable output logic in active "H" or active "L" • Selectable output form in CMOS or Nch open-drain • Operation temperature range: Ta = −40°C to +125°C • Lead-free (Sn 100%), halogen-free  Applications • Fan control • Air conditioning system • Mobile phone • Game console • Various electronic devices  Packages • SOT-23-5 • SNT-4A • HSNT-4 (1010) Seiko Instruments Inc. 1 TEMPERATURE SWITCH IC (THERMOSTAT IC) S-5844A Series  Block Diagrams 1.
