Description
The VN5E016AFH-E is a single channel high-side
driver manufactured using ST proprietary
VIPower™ M0-5 technology and housed in HPak
package. The device is designed to drive 12 V
automotive grounded loads, and delivering
protection and diagnostics. It also implements 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 auto
restart and overvoltage active clamp.
A dedicated analog current sense pin is
associated with every output channel providing
enhanced diagnostic functions. These functions
include fast detection of overload and short-circuit
to ground through power limitation indication,
overtemperature indication, short-circuit to VCC
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 share external sense resistor
with similar devices.
