Setting of the RESET signal delay time
Delay time can be set by capacitor C
L
and resistance R
L
connected to the output pin as shown below.
CL is charged by R
L
when Vcc is rising. The delay time caused by charging is determined by the
time constant of C
L
, R
L
and the threshold voltage of RESET pin. RESET IC discharges C
L
forcedly
when Vcc is falling. The delay time of RESET signal is determined by adding the delay time of single
RESET IC to each time.
