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. Standard Circuit R 100 k VDD Open RTH Open RTL DETH R*1 CL S-5842A Series CIN *1 100 k DETL VSS CL *1.
