8.1 Functions of Comparator and Programmable Gain Amplifier
The number of input pins of the comparators differs, depending on the product.
The programmable gain amplifiers and comparators have the following functions.
Comparators
• A comparator is equipped with two channels (CMP0, CMP1P
• Negative-side input pins (CMP0M, CMP1M) and a positive-side input pin (CMP0P, CMP1P) can be connected.
• The output signal of an programmable gain amplifier can be used as the positive-side input signal of a
• CMP0M and CMP1M pin inputs and the internal generation reference voltage (6 combinations for each
• The elimination width of the noise elimination digital filter can be selected.
• An interrupt request is generated when an overcurrent is detected (INTCMP0 and INTCMP1).
• The output signal of a comparator is connected to the timer array unit and sets the timer output pin (TOn) to a
Programmable gain amplifiers
• An programmable gain amplifier amplifies and outputs an analog voltage that is input. One among five
• The output signal of an programmable gain amplifier can be used as the positive-side input signal of a
• The output signal of an programmable gain amplifier can be selected as the analog input of an A/D converter.
Overcurrent detection function
The timer output pin (TOn) can be set to a Hi-Z state while an overcurrent flows by using an programmable gain
amplifier and a comparator. Furthermore, a function to set the pin to a Hi-Z state can be selected from the
following two functions.
• 2-stage overcurrent detection function
• Overcurrent/ electromotive force side detection function

CHAPTER 8 COMPARATORS/ PROGRAMMABLE GAIN AMPLIFIERS
There is no positive-side input pin for comparator 1 in the 78K0R/IB3. Only the signal output
from the programmable gain amplifier can be used for the input voltage.
