(3) When using resistors (auto switch)
Note
Caution The reset is driven from the QB-78K0MINI when a resistor is connected between RESET_IN
Remark All constants shown in this circuit are reference values.
Be sure to insert a buffer when connecting via resistors. In particular, if a power-on reset circuit is
connected directly, the time constant may become invalid due to RESET_OUT output from the QB-
78K0MINI, in which case a lack of drive capacity in the circuit where the reset occurs may prevent
proper detection of the reset. A reset circuit example is shown below.
