Description
The VN5E025AJ-E is a single channel high-side
driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
PowerSSO-12 package. The VN5E025AJ-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, over-temperature shut-off with autorestart 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 V
state and 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

1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device operates under
abnormal conditions this software must limit the duration and number of activation cycles.
