Hello,
I build my own board with a LTC4162-S. I'm trying to configure the telemetry and SMBALERT output pin but it didn't work as expected, or I miss something in the datasheet.
CONFIG_BITS_REG(@0x14) = 0x0E (by configuration, and verified by re-reading it) : telemetry_speed = 1 and force_telemetry_on = 1
I'm expecting to have a new data set of measures every 11ms. My CPU is waiting for a falling edge of SMBALERT but it is always to 1.
regs 0x36 (LIMIT_ALERTS_REG) and 0x0D (EN_LIMIT_ALERTS_REG) are both equal to 0x8000 so SMB alert IRQ is enabled and pending but the physical open-drain pin is still at 1.
Due to low-light condition, my solar panel is weakly charging (Vin=14.8V, Vout=12V, for a 12V battery). However according to the datasheet it should not affects the SMBALERT behaviour.
Any suggestion will help
Many thanks
