This state permits to manage the fault conditions in operating mode and it is entered by the
occurrence on one of the following conditions:
1. Vcc < VccOff (undervoltage fault on supply)
2. VREF < 2.0 V (undervoltage fault on VREF)
In this state the functions are:
– The HVSU generator is ON
– VREF is enabled in low source current mode (IREF < 10 mA)
– TPR is disabled
– OCP is disabled
– the drivers are disabled
In this state if Vcc reaches VccOn, the device enters the save mode otherwise, if
Vcc < VREF(OFF), also the C is turned off and the device will be ready to execute the startup
sequence.
