DESCRIPTION
The VN220 is a monolithic device designed in
STMicroelectronics
VIPower™
technology,
intended for driving resistive or inductive loads
with one side grounded. Built-in thermal shut-
down protects the chip from overtemperature and
short circuit. The open drain diagnostic output
indicates
open
circuit
(no
load)
and
overtemperature status.

FUNCTIONAL DESCRIPTIO N
The VN220 provides protection against a short circuit on
the output and senses the output current to detect an
open load. When one of these two faults is detected the
diagnostic output is taken low.
OPEN LOAD DETECTIO N
When the device is first turned on, only the auxiliary
DMOS device is turned on. If the load current remains
below 9mA (typical), the open load signal is active and
the diagnostic output is low. When the load current goes
above 9 mA the open load detection becomes inactive
and the diagnostic goes high. When the load current
exceeds 300 mA, the main DMOS (50 mΩ) turns on.
When the load current drops below 240 mA, the main
DMOS is turned off but no open load signal is generated
and the auxiliary DMOS is still turned on. If the load
current drops below 9mA, again the open load signal is
generated and the diagnostic output goes low.
SHORT CIRCUIT PROTECTION
Short circuit protection is achieved using the fast
response of the thermal shut-down circuit. The only
current limitation in this condition is the saturation current
of the DMOS devices and the external wiring resistance.
Under this condition the device can survive a short circuit
up to 30V across DMOS devices.
THERMAL PROTECTION
The device is internally protected against over
temperature by the thermal protection circuit. When the
device junction temperature exceeds the protection limit,
the output is latched off. To turn on the output again, the
input signal must be taken low to reset the latch, then
high again to turn on the output. If the junction
temperature has not yet cooled below the lower limit set
by the thermal sensing hysteresis, the device will remain
latched off.
NOTE: When an open load defect appears (or disappears) the
state of the diagnostic output changes only after the filtering time
(t
ol
). See open load waveform diagrams.
