Description
OT_EVENT
[7]
evnt
0x0
Over Temperature fault event flag. When Over temperature condition is detected, this bit is set to 1. When I2C writes '1'
to this bit, the event flag is cleared.
VIN_UV_EVENT
[6]
evnt
0x0
Under Voltage on VDD event flag. When Under Voltage (UVLO) condition is detected, this bit is set to 1. When I2C writes
'1' to this bit, the event flag is cleared.
OC_BUCK_EVENT
[4]
evnt
0x0
Over Current on BUCK OUT event flag. When the buck Over Current condition is detected (when BUCK_EN==1 &&
M_OC_BUCK==0), this bit is set to 1. When I2C writes '1' to this bit, the event flag is cleared.
OV_BUCK_EVENT
[3]
evnt
0x0
Over Voltage on BUCK OUT event flag. When the buck Over Voltage condition is detected (when BUCK_EN==1 &&
M_OV_BUCK==0), this bit is set to 1. When I2C writes '1' to this bit, the event flag is cleared.
UV_BUCK_EVENT
[2]
evnt
0x0
Under voltage on BUCK OUT event flag. When the under voltage condition (i.e. short circuit) is detected on the buck
(when BUCK_EN==1 && M_UV_BUCK==0), this bit is set to 1. When I2C writes '1' to this bit, this event flag is cleared.
