Infra Red Thermometer in TO-39
for high temperature thermometer guns
8.4.7 Sleep Mode
The MLX90616 can enter in Sleep Mode via the command âEnter SLEEP modeâ sent via the SMBus
interface. This mode is not available for the 5V supply version. To limit the current consumption to 2.5uA
(typical), the SCL pin should be kept low during sleep. MLX90616 goes back into power-up default mode (via
POR reset) by setting SCL pin high and then PWM/SDA pin low for at least tDDq=80ms. If EEPROM is
configured for PWM (EN_PWM is high), the PWM interface will be selected after awakening and if
PWM control [2], PPODB is 1 the MLX90616 will output a PWM pulse train with push-pull output.
