Standby Mode?

[VaTTeRGeR]

Is there a way to put the device into a software standby mode to reduce power consumption while VDD ist still present?

I want my host microcontroller, in a battery powered project, to go into deep sleep to reduce power consumption, but the MLX90640 is still drawing a LOT of current.

Setting the "Enable Data Hold" bit in register 0x800D, before shutting down the host mcu, reduced the power consumption by about 10mA. The sensor still draws about ~7 mA though, how can i reduce the standby power further, apart from cutting off VDD from the sensor?

PS: Reducing the refresh rate seems to have no effect on power consumption in hold mode, which makes sense.

Hi,
The MLX90640 has no sleep mode. The reason is that in a sleep mode the thermal distribution of the sensor would be totally different from the active state and the measurements after wake up would be totally off and require a long stabilisation time anyway.
