applications
Datasheet - production data
Features
General Inrush current active management by
power limitation Very low standby current 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Very low electromagnetic susceptibility In compliance with the 2002/95/EC
European directive Diagnostic functions Proportional load current sense High current sense precision for wide
current range Current sense disable Overload and short to ground (power
limitation) indication Thermal shutdown indication Protections Undervoltage shutdown Overvoltage clamp Load current limitation Self limiting of fast thermal transients Protection against loss of ground and loss
of VCC Overtemperature shutdown with auto

Applications All types of resistive, inductive and capacitive
loads Suitable as LED driver
Description
The VN5E016MH-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 VN5E016MH-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 enhanced diagnostic functions including
fast detection of overload and short-circuit to
ground through power limitation indication and
overtemperature indication.
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. Typical value with all loads connected.
