TH

– High Temperature Corner Set Pin

A resistor (R9) is connected between TH and ground to adjust the high corner temperature.

High Temperature Corner vs. R9

TA

– Output Duty Gap Adjust between High and Low Temperature Corners When Input Duty is 100%

A resistor (R7) is connected between TA and ground to adjust the output PWM duty gap between high temperature and low temperature corners

when the external input PWM duty is 100%.
