Description

The VN5E010AH is a single-channel high-side
driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
HPAK package. The VN5E010AH 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 auto­restart 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 Vcc diagnosis and
ON- 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
