Selection of Product Option
1. Description of product option
The S-5842A Series is a temperature switch IC (thermostat IC) which detects two points of temperature, and outputs a
signal to the exterior.
Users are able to select the combination of output type, form and logic, two detection temperatures (TDH, TDL), and
hysteresis temperature (THYSH, THYSL).
Output form: Set the output logic for each DETH pin and DETL pin.
CMOS output
Nch open-drain output
Output type: for DETH pin and DETL pin, users are able to select two types of output as follows.
Separate type: The DETH pin’s output inverts during detection of higher temperature
The DETL pin’s output inverts during detection of lower temperature
Integrate type: The DETH pin’s output inverts during detection of higher temperature
The DETL pin’s output inverts during detection of higher and lower temperature
Detection temperature (TDH, TDL):
T
DH is the detection temperature for higher temperature, TDL is the detection temperature for lower
temperature. Of two points of detection temperatures (TDH, TDL), select the detection temperature
that is to be set the higher accuracy (2.5°C accuracy).*1
The detection temperature for higher temperature is selectable in 20°C to 110°C, in 1°C step.
The detection temperature for lower temperature is selectable in 10°C to 110°C, in 1°C step.
Set two points of detection temperature so that the difference of detection temperature (TDET) is in 0°C
to 65°C. Users are able to set TDET in 0°C, 5°C, 10°C 60°C, 65°C.
The minimum operation voltage varies according to the detection temperature for lower temperature.
Detection temperature = 20°C to 110°C: VDD = 2.5 V min.
Detection temperature = 0°C to 110°C: VDD = 2.7 V min.
Detection temperature = 10°C to 110°C: VDD = 2.8 V min.
*1 Either of two detection temperatures (TDH, TDL), an accuracy of 2.5C is set only for the one that user specifies a
higher accuracy than the other (TDH, TDL).
Hysteresis temperature (THYSH, THYSL):
T
HYSH is the hysteresis temperature for detection temperature for higher temperature, THYSL is the
hysteresis temperature for detection temperature for lower temperature. These are selectable in 5°C,
2°C, 2°C, or 5°C.
5°C: Output recovers when temperature has dropped to 5°C from the detection temperature.
2°C: Output recovers when temperature has dropped to 2°C from the detection temperature.
2°C: Output recovers when temperature has risen to 2°C from the detection temperature.
5°C: Output recovers when temperature has risen to 5°C from the detection temperature.
Output logic: Set the output logic for each DETH, DETL pin in Ta detection temperature (TDH, TDL) or release
temperature (TDH THYSH, TDL THYSL).
(1) Hysteresis temperature: 5°C, 2°C
The output logic is "H" in Ta detection temperature
The output logic is "L" in Ta detection temperature
(2) Hysteresis temperature: 2°C, 5°C
The output logic is "H" in Ta release temperature
The output logic is "L" in Ta release temperature

3. Delay circuit
The S-5842A Series sets the noise suppression time (tdelay) via the delay circuit. By this, the S-5842A Series prevents
false detection operations of DETH pin and DETL pin output.
The followings are the operation of the DETH pin output when the output logic is "H".
3. 1 The temperature is the detection temperature or less
The output from a comparator is "H", and the DETH pin output is "L". Due to noise or others, the output from a
comparator is inverted to "L" once; however, the DETH pin output keeps "L" if this status is tdelay or shorter.
3. 2 The temperature exceeds the detection temperature
The output from a comparator gets "L". And the DETH pin output gets "H" after the period has passed tdelay
or longer.

Precautions
Either of two detection temperatures (TDH, TDL), an accuracy of 2.5C is set only for the one that user specifies a
higher accuracy than the other (TDH, TDL).
Set a capacitor (CIN) of 0.1 F or more between the VDD pin and VSS pin for stabilization.
To prevent error due to noise during power-on, set a capacitor (CL) of approx. 0.1 F for the DETH pin and the DETL
pin.
The S-5842A Series may oscillate by connecting a capacitor to the RTH pin and the RTL pin. Set the RTH pin and
the RTL pin open in use.
The DETH / DETL pin output a signal that of (Ta detection temperature) by short-circuit the RTH / RTL pin to VSS.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products,
including this IC, of patents owned by a third party.
