Low-Power Standby ModeStandby mode disables the ADC and reduces the sup-ply-current drain to 3µA (typ). Enter standby mode byforcing the STBY pin low

and does not go inactive until the temperature dropsbelow TLOW. Enable thermostat mode through the configuration reg-ister (Table 4), with one bit to
