5.12.1

Diode Faults

The EMC2103 actively detects an open and short condition on each measurement channel. When a

diode fault is detected, the temperature data MSByte is forced to a value of 80h and the FAULT bit is

set in the Status Register. When the External Diode 2 channel is configured to operate in APD mode,

the circuitry will detect independent open fault conditions, however a short condition will be shared

between the External Diode 2 and External Diode 3 channels.

If a diode fault occurs on the hardware defined shutdown channel, then no temperature comparison is

performed. The SYS_SHDN pin will not be asserted.

GPIOs

The EMC2103-2 and EMC2103-4 contain two dedicated GPIO pins. The GPIO pins can be individually

configured as an input or an output and as a push-pull or open-drain output. Additionally, each GPIO

pin, when configured as an input, can be individually enabled to trigger an interrupt when they change

states.
