Both functions can be used
set the pin to a Hi-Z state, and inputting the same signal to the positive-side inputs of comparators 0 and 1.
• 2-stage overcurrent detection function
• Overcurrent/ electromotive force side detection function
Note
<1> Reference voltage of comparator 0 < input signal voltage < reference voltage of comparator 1
<2> Reference voltage of comparator 1 < input signal voltage
<1> Input signal voltage (electromotive force) < comparator 0, or comparator 1 < input signal voltage
There is no positive-side input pin for comparator 1 in the 78K0R/IB3. When using the overcurrent
detection function, input the signal that is output by the programmable gain amplifier to the positive-side
input of both comparator 0 and comparator 1.
→ Set the TOn pin to a Hi-Z state.
→ Set the TOn pin to a Hi-Z state.
(overcurrent)
→ Set the TOn pin to a Hi-Z state.
Remarks.1 For details of overcurrent detection function, see 7.5 Overcurrent Detection Function.
Timer output is automatically restarted in synchronization with the timer cycle when the input signal
voltage is lower than the reference voltage of comparator 0.
Timer output is automatically restarted in synchronization with the next timer cycle by setting a
register, when the input signal voltage is lower than the reference voltage of comparator 0.
Timer output is automatically restarted in synchronization with the timer cycle when the input
signal voltage is higher than the reference voltage of comparator 0 or when it is lower than the
reference voltage of comparator 1.
