Description

The VND5E050J-E and VND5E050K-E are

double channel high-side drivers manufactured in

the ST proprietary VIPower M0-5 technology

and housed in the tiny PowerSSO-12 and

PowerSSO-24 packages.

The

VND5E050J-E and VND5E050K-E

are

designed to drive automotive

grounded loads

delivering protection, diagnostics and easy 3V

and 5V CMOS-compatible interface with any

microcontroller.

The devices integrate 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 active low digital status pin is

associated with every output channel in order to

provide Enhanced diagnostic functions including

fast detection of overload and short-circuit to

ground, over temperature indication, short-circuit

to V

diagnosis and on & off-state open-load

detection.

The diagnostic feedback of the whole device can

be disabled by pulling the STAT_DIS pin up, thus

allowing wired-ORing with other similar devices.

VND5E050K-E Application information If the calculated power dissipation leads to a large resistor or several devices have to share the same resistor then ST suggests to utilize Solution 2 (see below). 3.1.2 Solution 2: diode (DGND) in the ground line A resistor (RGND=1kshould be inserted in parallel to DGND if the device drives an inductive load. This small signal diode can be safely shared amongst several different HSDs.
