We designed a TEC driver with ADN8835 IC, with the referance designs in the datasheet and demo board documents, it as a digital PID design, with 4.5V Voltage out limit, 2.5A max current out limit settings.
In the case we apply around 2.5V to the IN2P Dac input and draw some current more than (1A) from the output, the LDR-GND pins are becoming short-circuited and the IC breaks down. We brokedown 3 of ICs. Detailed schematic is below. Can you help us to understand the problem?
