Test pin 1. This pin is used for test purposes by NPC. It has a built-in pull-up resistor. Leave

open for normal operation.

Output.

SM6611×AH: Open-drain output. A pull-up resistor of 100kΩ should be connected to this

O

pin. Goes LOW when the switch preset temperature is exceeded.

SM6611×BH: CMOS output. Goes LOW to HIGH when the switch preset temperature is

exceeded.
