8.4.7 Sleep Mode
The MLX90614 can enter in Sleep Mode via the command “Enter SLEEP mode” 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. MLX90614 goes back into power-up default mode (via
POR reset) by setting SCL pin high and then PWM/SDA pin low for at least t
=80ms. If EEPROM is
DDq
configured for PWM (EN_PWM is high), the PWM interface will be selected after awakening and if
PWM control [2], PPODB is 1 the MLX90614 will output a PWM pulse train with push-pull output.

First data is available 0.25 seconds (typ) after exit from Sleep is done. On-chip IIR filter is skipped for the very
first measurement. All measurements afterwards pass the embedded digital filtering as configured in
