Description
The VN5E160AS-E is a single-channel high-side
driver manufactured in the ST proprietary
VIPower™ M0-5 technology and housed in the
tiny SO-8 package. The VN5E160AS-E is
designed to drive 12 V automotive grounded
loads delivering protection, diagnostics and easy
3 V and 5 V 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, overtemperature shut-off with
auto-restart and overvoltage 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,
overtemperature indication, short-circuit to V_CC
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.
