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.
