on the VPWR pin. Characteristics are provided from 6.0 V to
20 V for the device. The VPWR pin supplies power to internal
regulator, analog, and logic circuit blocks. The VDD supply is
used for Serial Peripheral Interface (SPI) communication in
order to configure and diagnose the device. This IC
architecture provides a low quiescent current sleep mode.

MCU INTERFACE AND OUTPUT CONTROL
MCU through SPI. A pulse width modulation control module
allows improvement of lamp lifetime with bulb power
regulation (PWM frequency range from 100 to 400 Hz) and
addressing the dimming application (day running light). An
analog feedback output provides a current proportional to the
load current or the temperature of the board. The SPI is used
to configure and to read the diagnostic status (faults) of high
side outputs. The reported fault conditions are: open-load,
short-circuit to battery, short-circuit to ground (over-current
and severe short-circuit), thermal shut-down, and under/
over-voltage. Thanks to accurate and configurable over-
current detection circuitry and wire-harness optimization, the
vehicle is lighter.
