mode
Voltage to disable boost mode
00 â Vbhot1 (33% of REGN or 55°C
w/ 103AT thermistor)
01 â Vbhot0 (36% of REGN or 60°C
w/ 103AT thermistor)
10 â Vbhot2 (30% of REGN or 65°C
w/ 103AT thermistor)
11 â Disable boost mode thermal
protection.
Default: Vbhot1 (00)
Note: For BHOT[1:0] = 11, boost mode
operates without temperature monitor
and the NTC_FAULT is generated based
on Vbhot1 threshold
