*For the correctness of the error message, MBI5038 releases the error detection period only when receiving one

LE pulse containing 0 CLK and CLK is active. During the error detection period, MBI5038 will force OUT_B off and

perform the compulsory error detection. MBI5038 releases the error detection period when LE falling (any

commands).

** Chip releases the error detection period when LE falling (any commands).

Thermal Flag

Thermal flag 1 is over-temperature alarm, and thermal flag 2 is thermal shutdown. When the IC temperature is over

140°C, thermal flag 1 will report “0”. When the IC temperature is under 120°C, thermal flag 1 will recover to “1”.

When the IC temperature is over 160°C, the thermal flag 2 will become “0”, and the output channels will be shut

down. The thermal shutdown status is latched until power cycling or a wakeup command issued from the controller.
