Notes: HT7510’s substrate connected to VDD and HT84018-0D’s substrate connected to VSS.

LOWC is connected to an external resistor for adjusting the detector level of a low voltage

detector. Open the pin when not in use.

OSCI, OSCO are connected to an external resistor, and form an RC oscillator with a built-in

capacitor for SYSTEM clock (32kHz)

RS, RF, SC constitute an alternating RC oscillator, which allows one oscillator, namely RS or

RF, active at a time.

REF (reference resistor) is a resistor value equal to 503ET sensor in 37.0 °C or 98.6°F

RENSOR is a 503ET thermistor.
