Description

The VNQ5E050MK-E is a quad channel high-side

driver manufactured in the ST proprietary

VIPower M0-5 technology and housed in the tiny

PowerSSO-24 package. The VNQ5E050MK-E is

designed to drive 12V automotive grounded loads

delivering protection, diagnostics and easy 3V

and 5V 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 over-voltage 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.
