DESCRIPTION
The VN380 is a monolithic device made using
STM VIPower Technology, intended for driving
inductive loads. The inputs are CMOS
compatible. The diagnostic output provides an
indication of open load and demagnetization
mode. Built-in thermal shut-down protects the
chip from over-temperature. In case or
over-current or over-temperature or over-voltage
the product will automatically operate in
recirculation mode.

FUNCTIONAL DESCRIPTION
- CURRENT CUT OFF
When the load current rise above the current cut off level, S1 is automatically switched off and the
devices operates in recirculation mode (S2 active). S1is latched off until A goes low and high again.
This default is not displayed by diagnostic flag.
- OPEN LOAD
If the load current is below the open load current level, the flag of the open load block is activated but
this default is displayed by the diagnostic output on the falling edge of input B and the diagnostic output
is latched at low level until input A goes low and high again. In case an open load is detected during an
active phase of input B, but disappears before a falling edge of input B, this default is not dispayed by
the diagnostic flag (see open load waveforms).
- THERMAL SHUTDOWN
The device is internally protected against over temperatures by the thermal circuit protection. When the
device junction temperature exceeds the protection limit, S1 is automatically switched off. Therefore the
device operates in recirculation mode (S2 active). S1 remain latched off until Vpwr1 goes low and high
again. This default is not dispayed by the diagnostic flag.
OVERVOLTAGE
During the ON state of S1 switch, if Vpwr1 or Vpwr2 is rising above the threshold detection S1 is
automatically switched off, therefore the device operates in recirculation mode.
