DESCRIPTION The VN330SP is a monolithic device made using
STMicroelectronics VIPower Technology,
intended for driving four indipendent resistive or
inductive loads with one side connected to
ground.
Active current limitation avoids dropping the
system power supply in case of shorted load.
Built-in thermal shut-down protects the chip from
over temperature and short circuit.
The open drain diagnostic output indicates short
circuit and overtemperature conditions.

ELECTRICAL CHARACTERISTICS (continued)LOGIC INPUT (Each Channel)
note 1 : The input voltage is internally clamped at 32V minimum, it is possible to connect the input pins to an higher voltage via an external
resistor calculate to not exceed 10 mA.
PROTECTION AND DIAGNOSTICS
(•) Status determination > 100 μs after the switching edge.
Note: If INPUTn pin is left floating the corresponding channel will automatically switch off. If GND pin is disconnetted, all channels will switch
off provided VCC does not exceed 36V
