Description
The VN380SP is monolithic device made using
STMicroelectonics 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 shutdown
protects the chip from over temperature. In case
or over current or over temperature or overvoltage
the product will automatically operate in
recirculation mode.

3 Functional description
3.1 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). S1 is latched off until A goes low
and high again.
This default is not displayed by diagnostic flag.
3.2 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 on Figure 5).
3.3 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.
3.4 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.
