CLRC663+ : leakage current in standby mode

Question asked by Olivier GIARD on Sep 28, 2018


I have a board with CLRCL663+ drived by an STM32L4.

CLRCL has VDD=3.3v (same voltage for STM32) and TVDD=5V
When I apply 1 to the POWERDN pin of the CLRC the power consumption is nearly 24uA
When the the POWERDN pin is 0 and I set the standby bit (bit 7, register 00h) to 1, the IC goes in standby mode but the power consumption is nearly 400/500uA instead of the 8uA in the datasheet.

Does anyone has this problem too?
