Description

The VN5E025ASO-E is a single channel high­side driver manufactured using ST proprietary
VIPower
SO-16L package. The device is designed to drive
12 V automotive grounded loads, and to provide
protection and diagnostics. It also implements a
3 V and 5 V CMOS-compatible interface for use
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 auto­restart and overvoltage active clamp. A dedicated
analog current sense pin is associated with every
output channel providing enhanced diagnostic
functions including fast detection of overload and
short-circuit to ground through power limitation
indication, overtemperature indication, short­circuit to V
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
share the external sense resistor with 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.
