My Ifault pin is pulled up through a 100k resistor to 3.3V. When I apply a dummy load of 3A from ACN to GND, well above the 128mA input current limit of the 0x3f register (by setting 0x3f to 0x0100. nothing causes a trip. is there something wrong with my setyup?
here are my registers in format:
register: High byte, low byte
0x12: 0x19, 0x04
0x14: 0x08, 0x00
0x15: 0x32, 0x00
0x3f: 0x01, 0x00
because of these register values, acoc should be enabled. I draw 1amp of current, way above 2x the limit of acoc, and the ifault doesn't trip. I've also noticed that the outside pin is exactly correct when charge current is chosen (200mV @ 1A), but the iout pin is wildly inaccurate when input current is chosen (75mV @ 1A charging). this doesnt make sense because the input current is the charging current plus what it takes to run the ic. I've verified we are using a 10m resistor between acn and acp.
