21 / 139 page  NXP Semiconductors 35FS4500-35FS6500-ASILB Grade 0 safety power system basis chip with CAN FD transceiver TA = –40 °C to 150 °C, unless otherwise specified. VSUP = VSUP_UV_L to 36 V, unless otherwise specified. All voltages referenced to ground. When 28 V < VSUP < 36 V, thermal dissipation must be considered (see Figure 27). Symbol Parameter Min. Typ.
