activated (i.e. driven low). This device is equipped with hysteresis, V
noise immunity under transient conditions.
For available OVLO thresholds and hystereses, please see the
Thermal shutdown
If the STBP120 internal junction temperature exceeds the T
switch is turned off and the fault indication output FLT is driven low.
To improve thermal stability, this circuit has a 20 °C hysteresis, T
