FS6500-FS4500-ASILD

Safety power system basis chip with CAN FD and LIN transceivers

TA = –40 °C to 125 °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 32).
