FS6500-FS4500-ASILD

Safety power system basis chip with CAN FD and LIN transceivers

diagnostic. The LIN consortium specification does not specify electrical parameters for this baud rate. The

communication only must be guaranteed. In LPOFF mode, the LIN transistor is off, and this pin is pulled up to

VSUP3. LIN has integrated ESD protection and extremely high robustness versus external disturbance, such as

EMC and electrical transients.

11.13 Multiplexer output MUX_OUT

The MUX_OUT pin (Figure 12) delivers analog voltage to the MCU ADC input. The voltage to be delivered to

MUX_OUT is selected via the SPI, from one of the following parameters:

• VSENSE

• VIO_0

• VKAM

• Internal 2.5 V reference

• Internal die temperature sensor T(°C) = (VAMUX – VAMUX_TP)/VAMUX_TP_CO + 165

Voltage range at MUX_OUT is from GND to VDDIO (3.3 V or 5.0 V)

11.14 I/O pins (I/O_0:I/O_5)

The FS6500/FS4500 includes five multi-purpose I/Os (I/O_0 to I/O_5). I/O_0 and I/O_4 are load dump proof

and robust against ISO 7637(14) pulses. An external serial resistor must be connected to those pins to limit

the current during ISO pulses. I/O_2 and I/O_3 are not load dump proof. I/O_5 requires an external protection

(resistor and Zener diode) to be load dump proof and robust against ISO 7637(14) pulses.
