POWER SUPPLY
VPWR pin. Characteristics are provided from 6.0 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.
Applying V
the Normal Mode. The device will transit to Fail-safe mode in
case of failures on the SPI (watchdog timeout).

automotive loads with high inrush current, as well as motors
and all types of resistive and inductive loads. This N-channel
MOSFET with a 2.0 mΩ RDS(ON), is self-protected and

MCU through the SPI. With a dedicated SPI command, it is
possible to independently turn on and off several loads that
are PWM’d at the same frequency, and duty cycles with only
one PWM signal. An analog feedback output provides a
current proportional to the load current. The SPI is used to
configure and to read the diagnostic status (faults) of high
side output. The reported fault conditions are: open load,
short-circuit to ground (OCLO-resistive and OCHI-severe
short-circuit), thermal shutdown, and under/over-voltage.
