53 / 153 page  NXP Semiconductors FS6500-FS4500-ASILD Safety power system basis chip with CAN FD and LIN transceivers 12.6 Input voltage range Due to the flexibility of the pre-regulator, the device can cover a wide battery input voltage range. However, a more standard voltage range can still be covered using only the buck configuration. aaa-037761 No operation Risk of damage No operation Risk of damage Extended voltage range Potencial VPRE thermal limitation Extended voltage range Potencial VPRE thermal limitation Extended voltage range VPRE output current limitation Extended voltage range VPRE output current limitation No operation Buck-boost 2.7 V 6.0 V 19 V 28 V 40 V 4.5 V Buck only No operation Extended voltage range AMUX limitation Extended voltage range AMUX limitation Normal voltage range Normal voltage range VSUP VSUP_UV_7 Figure 32. Input voltage range • VSUP > 28 V: Potential VPRE thermal limitation RDS(on), Current limitation and overcurrent detection are specified for VSUP < 28 V. • VSUP > 19 V: MUX_OUT limitation VSENSE and IO_0 maximum analog input voltage range is 19 V. Internal 2.5 V reference voltage accuracy degraded. • Buck only, VSUP < VSUP_UV_7: CAN communication is guaranteed for VSUP > 6.0 V. LIN communication stopped when VSUP < 7.0 V if LIN_J2602_DIS bit is not set. For VCCA and VAUX 5.0 V configuration, undervoltage triggers at low VSUP (See Section 9, VCCA_UV_5 and VAUX_UV_5). 12.7 Power management operation A thermal sensor is implemented as close as possible to the pass transistor of each regulator (VPRE, VCORE, VCCA, VCAN) and an associated individual thermal shutdown (TSD) protects these regulators independently. When the TSD threshold of a specific regulator is reached, this regulator only is switched off and the information FS6500-FS4500-ASILD All information provided in this document is subject to legal disclaimers. © 2024 NXP B.V.
