Description

The VN340SP-33-E is a monolithic device made
using STMicroelectronics VIPower technology,
intended for driving four independent 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
overtemperature and short circuit. The open drain
diagnostic output indicates overtemperature
conditions. Each I/O is pulled down when
overtemperature condition of the relative channel
is verified.
