Description
The VNQ5E160AK-E is a double channel high-
side driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
PowerSSO-24 package. The VNQ5E160AK-E is
designed to drive 12V automotive grounded loads
delivering protection, diagnostics and easy 3V
and 5V CMOS compatible interface with any
microcontroller.
The device integrates advanced protective
functions such as load current limitation, inrush
and overload active management by power
limitation, over-temperature shut-off with
auto-restart and over-voltage active clamp. A
dedicated analog current sense pin is associated
with every output channel in order to provide
Ehnanced diagnostic functions including fast
detection of overload and short-circuit to ground
through power limitation indication, over-
temperature indication, short-circuit to Vcc
diagnosis and on & off state open load detection.
The current sensing and diagnostic feedback of
the whole device can be disabled by pulling the
CS_DIS pin high to allow sharing of the external
sense resistor with other similar devices.
