FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
PREVIOUS ADDRESS SOA4 : SOA0 = A₁A₀001
(PWMR_S)
The returned data contains the programmed values in the
PWMR register for the output selected with A₁A₀.
PREVIOUS ADDRESS SOA4 : SOA0 = A₁A₀010
(CONFR0_S)
The returned data contains the programmed values in the
CONFR0 register for the output selected with A₁A₀.
PREVIOUS ADDRESS SOA4 : SOA0 = A₁A₀011
(CONFR1_S)
The returned data contains the programmed values in the
CONFR1 register for the output selected with A₁A₀.
PREVIOUS ADDRESS SOA4 : SOA0 = A₁A₀100
(OCR_S)
The returned data contains the programmed values in the
OCR register for the output selected with A₁A₀.
PREVIOUS ADDRESS SOA4 : SOA0 = 00101 (GCR)
The returned data contains the programmed values in the
GCR register.
PREVIOUS ADDRESS SOA4 : SOA0 = 00111
(DIAGR0)
The returned data OD2 reports logic [1] in case of PWM
clock on IN0 pin is out of specified frequency range.
The returned data OD1 reports logic [1] in case of
calibration failure.
The returned data OD0 reports logic [1] in case of over-
temperature prewarning (temperature of GND flag is above
T_OTWAR).
PREVIOUS ADDRESS SOA4 : SOA0 = 01111
(DIAGR1)
The returned data OD4: OD1 report in real time the state
of the direct input IN[3:0].
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 time-out as
explained in the following Table 23.

PREVIOUS ADDRESS SOA4 : SOA0 = 10111
(DIAGR2)
The returned data is the product ID. Bits OD2:OD0 are set
to 100 for Protected Quad 35mΩ High Side Switches.
DEFAULT DEVICE CONFIGURATION
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 severe short-circuit
protection, the under-voltage, and the over-temperature
protection. The auto-retry feature is enabled,
• Open-load in ON and OFF state and HS shorted to VPWR
detections are available,
• No current recopy and no analog temperature feedback
active,
• Over-voltage protection is enabled,
• SO reporting fault status from HS0,
• VDD failure detection is disabled.
