Description
The VND7140AJ-E is a double 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,
providing 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 V_CC 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.
