Description of Functions and Examples of Constant Setting continued  
(5) Temperature monitor function  
The TO Pin Output Current (ITO) is supplied from the TO pin from the built-in constant current circuit. This current value  
can be adjusted in accordance with the resistance value between the TC pin and the VEE2 pin. Furthermore, the TO pin  
voltage is converted to Duty and outputs the signal to the SENSOR pin.

where:  
푇푂 is the TO pin Output Current.  
푇퐶 is the TC pin Voltage.  
푇퐶 is the resistance to determine the desired 푇푂  
.

The SENSOR Duty is calculated according to the following calculating formula.  
(VTO < 1.35 V):  
ꢏꢐꢑꢏꢒꢀ ꢓ푢푡푦 = ꢄ0 [%]  
(1.35 V VTO < 2.5 V):  
ꢏꢐꢑꢏꢒꢀ ꢓ푢푡푦 = ꢁꢍ × 푇푂 − ꢁꢁ.ꢍ [%]  
(2.5 V VTO 3.84 V):  
ꢏꢐꢑꢏꢒꢀ ꢓ푢푡푦 = ꢁꢍ × 푇푂 − ꢁꢍ.9  
[%]  
(3.84 V < VTO):  
ꢏꢐꢑꢏꢒꢀ ꢓ푢푡푦 = 90 [%]  
where:  
ꢏꢐꢑꢏꢒꢀ ꢓ푢푡푦 is the duty cycle obtained by converting the TO pin voltage.  
푇푂 is the TO pin voltage.
