The returned data OD2 reports logic [1] in case of PWM
clock on IN0 pin is out of specified frequency range.
The returned data is the product ID. Bits OD2:OD0 are set
to 000 for Protected Dual 10 mΩ and 12 mΩ High Side
Switches.
The returned data OD1 reports logic [1] in case of
calibration failure.
DEFAULT DEVICE CONFIGURATION
The returned data OD0 reports logic [1] in case of an over-
temperature prewarning (temperature of the GND flag is
above TOTWAR).
The default device configuration is explained below:
• HS output is commanded by corresponding IN input or On
bit through SPI. The medium slew rate is used,
• HS output is fully protected by the Xenon over-current
profile by default, the severe short-circuit protection, the
under-voltage and the over-temperature protection. The
autoretry feature is enabled,

The returned data OD4: OD1 report in real time the state
of the direct input IN[3:0].
• Open-load in ON and OFF state and HS shorted to VPWR
detections are available,
• No current recopy and no analog temperature feedback
active,
The OD0 indicates if the watchdog is enabled (set to logic
[1]) or not (set to logic [0]). OD4:OD1 report the output state
in case of Fail-safe state due to watchdog timeout as
explained in the following Table 24.
• Over-voltage protection is enabled,
Table 24. Watchdog Activation Report
• SO reporting fault status from HS0,
• VDD failure detection is disabled.
