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
recirculationmode.

FUNCTIONAL DESCRIPTION
- CURRENT CUT OFF
When the load current rise above the current cut off level, S1 is automatically switched off and the
devicesoperates inrecirculationmode (S2 active).S1is latched off until Agoes low and highagain.
This default is not displayed by diagnostic flag.
- OPENLOAD
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 diagnosticoutput on the fallingedge of input B and the diagnosticoutput
is latched at low level untilinput 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 diagnosticflag (see openload waveforms).
- THERMAL SHUTDOWN
The device is internally protected against over temperaturesby the thermal circuit protection. When the
device junction temperature exceeds the protection limit, S1 is automaticallyswitched off. Therefore the
device operates in recirculation mode (S2 active). S1 remain latched off until V
again. This default is not dispayed by the diagnostic flag.
OVERVOLTAGE
During the ON state of S1 switch, if V
pwr1
or V
is rising above the threshold detection S1 is
pwr2
automaticallyswitchedoff, thereforethe deviceoperatesin recirculationmode.
