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 VCC 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.
Max supply voltage VCC 41V
Operating voltage range VCC 4.5 to 28V
Max On-State resistance (per ch.)
RON 50 mΩ
Current limitation (typ) ILIMH 27 A
Off-state supply current IS2 µA(1)

Table 8. Protections (1)
1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device is subjected to
abnormal conditions, this software must limit the duration and number of activation cycles.
