Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.

Application circuit example(Constant values are for reference)
2) PWM input application 2
It is an example of the application of inverting the external PWM input, and controlling the rotational speed. In this
application, if the external PWM input is OPEN, it controls by the set maximum rotational speed. Minimum rotational
speed cannot be set.
SIG
Circuit that input direct PWM
(Ref.) PWM input frequency is
20kHz to 50kHz
PWM
To be disable TH terminal, set
TH voltage more than OSC
high level (Typ 2.5V) and less
than REF voltage (Typ 5.0V).
