Calculation examples
CTN(25°C) = 47K
CTN(55°C) = 10K
CTN(-10°C) = 300K
CTN(-10°C) x VCC = ( CTN(-10°C) + R1 ) x BAT-TEMP (full range)
R1= 47K
"
BAT-TEMP(-20°C) = 2.42V
BAT-TEMP(55°C) = 0.49V
R(-20°C) = R1//CTN(-10°C) = 40K
R(+55°C) = 8K
With C= 10nF::
RC(-20°C) = 400µs
RC(+55°C) = 80µs
2.13 ON / ~OFF
This input is used to switch ON or OFF the WISMO Quik Q2403 Series module.
A high level signal has to be provided on the pin ON/~OFF to swith ON the
module. The level of the voltage of this signal has to be maintained between
2.4V and VDD during a minimum of 500ms. This signal can be left at high level
until switched off.
To be able to switch OFF the module, the pin ON/OFF has to be released.
Through the firmware, the module can be switched off (using the CPOF
command).
