7 / 213 page  2 Maximum ratings 2.1 Operating range Within the operating range the part operates as specified and without parameter deviations. The device may not operate properly if maximum operating conditions are exceeded. Once taken beyond the operative ratings and returned back within, the part recovers with no damage or degradation. Additional supply voltage and temperature conditions are given separately at the beginning of each electrical specification table. All voltages are related to the potential at substrate ground pin. Table 2. Operating conditions Symbol Parameter Condition Min Typ Max Unit VS Global Supply voltage 3(1) - 29 V FBB Boost output 7.7 - 29 V VIN12 BUCK1 and BUCK2 supply pin 7.7 - 29 V VIN3 BUCK3 supply pin 3 - 7 V VIO Digital interface supply pin 3 - 5.5 V 1. VS operating range from 3 V up to Vfbb_regx is intended as a transitory time during cranking conditions. 2.1.1 Supply voltage ranges All SPI communication, logic and oscillator parameters work down to VS = VPORVS_F and are specified accordingly: • SPI thresholds • Oscillator frequency (delay times correctly elapsed) • Internal register status correctly kept (reset at default values for VS < VPORVS_F) • Reset threshold correctly detected 2.2 Absolute maximum ratings Maximum ratings are absolute ratings; exceeding any one of these values may cause permanent damage to the integrated circuit. All voltages are related to the potential at substrate ground pin. Table 3.
