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.
