Each voltage regulator has a dedicated I2C bit that is used to bypass the fault detection
mechanism for each specific fault.
SWx_ILIM_BYPASS
• 0 = ILIM protection enabled
• 1 = ILIM fault bypassed
SWx_OV_BYPASS
• 0 = OV protection enabled
• 1 = OV fault bypassed
SWx_UV_BYPASS
• 0 = UV protection enabled
• 1 = UV fault bypassed

SWx
SWx_ILIM_BYPASS
SWx_UV_BYPASS
SWx_OV_BYPASS
The default value of the OV_BYPASS, UV_BYPASS and ILIM_BYPASS bits upon power
up can be configured by their corresponding OTP bits.
Bypassing the fault detection prevents the specific fault from starting any of the protective
mechanism:
• Increment the counter
• Start the fault timer
• Disable the regulator if the corresponding _STATE bit is 0
