XC6190 Overview
The XC6190 series are timer reset ICs that supply a reboot signal to the system when āLā voltage is input into the SW1, SW2 pins for a set time (reboot delay time) using two switches (physical buttons). On type A, the reboot delay time (TDL) can be set as desired by changing the external resistance RT within the range 1s to 20s. On type B, TDL is fixed internally.
