VDIFF_LAT

Selects if the VDiff fault is to be a latched type fault.

0 = Unlatched fault

1 = Latched fault

MAX_CUR

Configures the second stage to draw maximum power when the boost output

voltage exceeds boost overvoltage protection threshold VBST > VBOP(th), trig-

gering a boost overvoltage fault.

0 = Disable

1 = Enable

WAKEUP[3:0]

Configures the 8-bit code value corresponding to temperature threshold

TempWakeup. Upon power-up the system will enter an external overtempera-

ture fault disabling the power train, unless the external temperature measured

at the external NTC is below TempWakeup. If the temperature drops below this

threshold, the device will clear all overtemperature faults. The setting is an off-

set to TempeOTP (see “Configuration 59 (Config59) – Address 91” on page 48

for configuring TempeOTP).

The equation above is setting 8-bit code, CODETEMPWakeup, corresponding to

temperature TempWakeup, which is in degrees Celsius. The wakeup tempera-

ture code is configured as an offset from the eOTP temperature code and the

shutdown temperature code is configured as an offset from the wakeup tem-

perature code; TempeOTP < TempWakeup < TempShutdown.
