mode
Voltage to disable boost mode
00 – V_bhot1 (33% of REGN or 55°C
w/ 103AT thermistor)
01 – V_bhot0 (36% of REGN or 60°C
w/ 103AT thermistor)
10 – V_bhot2 (30% of REGN or 65°C
w/ 103AT thermistor)
11 – Disable boost mode thermal
protection.
Default: V_bhot1 (00)
Note: For BHOT[1:0] = 11, boost mode
operates without temperature monitor
and the NTC_FAULT is generated based
on V_bhot1 threshold
00 – 60°C, 01 – 80°C, 10 – 100°C, Default: 120°C (11)
