Description

The VND5E025LK-E is a double channel high-

side drivers manufactured in the ST proprietary

VIPower M0-5 technology and housed in the tiny

PowerSSO-24 package. The VND5E025LK-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, over-temperature 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

Ehnanced diagnostic functions including fast

detection of overload and short-circuit to ground

through power limitation indication, over-

temperature indication, short-circuit to Vcc

diagnosis and ON & 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.

– Reverse battery protected (see

– Electrostatic discharge protection

All types of resistive, inductive and capacitive

loads

Suitable as LED driver

for automotive applications
