In datasheet, chapter 7.3.7.1, it says “The Auto Reverse mode operation will be automatically enabled if the following conditions are valid: 1. SRN voltage above VSRN_OK 2. VAC outside the ACOV / ACUV operating window, or VAC < VVAC_OK, or VAC > VVAC_INT_OV 3. Auto Reverse mode operation is enabled (EN_AUTO_REV = 1) 4. Voltage at TS (thermistor) pin is within range configured by Reverse Temperature Monitor as configured by BHOT and BCOLD register bit”
I would like to know if VSRN_OK is a fixed value? If so, what exactly is it? Is it possible to program it via resistors or configure it through registers?
During my testing, I found that when the VAC undervoltage in reverse mode (80% VAC_REV) occurs, the reverse mode is turned off, but the automatic reverse is not disabled. This causes the reverse mode to repeatedly turn on and off.
