■ Suitable as LED driver
Description
The VN5E016AH-E is a single channel high-side
driver manufactured in the ST proprietary
VIPower™ M0-5 technology and housed in the
tiny HPak package. The VN5E016AH-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 to provide
enhanced diagnostic functions. These functions
include fast detection of overload and short-circuit
to ground through power limitation indication,
overtemperature indication, short-circuit to V
diagnosis and ON-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 is subjected to
abnormal conditions, this software must limit the duration and number of activation cycles
