Overtemperature (OTE), overload (OLP), or undervoltage (UVP) junction temperature higher than
0
125°C (overtemperature warning)
0 OLP or UVP; junction temperature higher than 125°C (overtemperature warning)
1 OLP or UVP; junction temperature lower than 125°C
0 Junction temperature higher than 125°C (overtemperature warning)
1 Junction temperature lower than 125°C and no OLP or UVP faults (normal operation)
