– Configurable latch-off on overtemperature
or power limitation with dedicated fault
reset pin
– Reverse battery with external components
– Electrostatic discharge protection
Applications
All types of automotive resistive, inductive and
capacitive loads
Specially intended for Automotive Turn
Indicators (up to 2 x P27W or SAE1156 and
R5W paralleled or LED Rear Combinations)
Description
The VN7020AJ-E is a single channel high-side
driver manufactured using ST proprietary
VIPower® technology and housed in
PowerSSO-16 package. The device is designed
to drive 12 V automotive grounded loads through
a 3 V and 5 V CMOS-compatible interface, and to
provide protection and diagnostics.
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown with configurable
latch-off. A FaultRST pin unlatches the output in
case of fault or disables the latch-off functionality.
A dedicated multifunction multiplexed analog
output pin delivers sophisticated diagnostic
functions including high precision proportional
load current sense, supply voltage feedback and
chip temperature sense, in addition to the
detection of overload and short circuit to ground,
short to VCC and OFF-state open-load.
A sense enable pin allows OFF-state diagnosis to
be disabled during the module low-power mode
as well as external sense resistor sharing among
similar devices.
