TEMPERATURE SWITCH IC (THERMOSTAT IC)
Rev.2.2_00
The S-5843A 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-5843A Series restores the output voltage
when the temperature drops to the level of release temperature.
The S-5843A Series operates at the lower power supply voltage of 1.65 V and its current consumption is 4.5 μA typ. due to
CMOS configuration.
A temperature sensor with the negative temperature coefficient, a reference voltage generation circuit, a comparator and a
delay circuit are integrated on one chip, and enclosed into the packages SOT-23-5 and SNT-6A.
Features
Detection temperature:
TDET = +40°C to +120°C, +1°C step, detection accuracy: ±2.5°C
Low voltage operation:
VDD = 1.65 V min.
Low current consumption:
IDD = 4.5 μA typ. (Ta = +25°C)
Hysteresis temperature:
selectable in 2°C, 4°C, 10°C or 20°C
Selectable output logic in active "H" or "L"
Selectable output form in CMOS or Nch open drain
Prevent functions for false detection operation and false release operation
Operation temperature range:
Lead-free, Sn 100%, halogen-free*1
Ta = 40°C to +125°C
*1. Refer to "Product Name Structure" for details.
