VND5E050AJ-E
VND5E050AK-EDouble channel high side driver with analog current sense
for automotive applications
Features General Inrush current active management by
power limitation Very low standby current 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Very low electromagnetic susceptibility In compliance with the 2002/95/EC
european directive Very low current sense leakage Diagnostic functions Proportional load current sense High current sense precision for wide
currents range Current sense disable Off-state open load detection Output short to VCC detection Overload and short to ground (power
limitation) indication Thermal shutdown indication Protections Undervoltage shutdown Overvoltage clamp Load current limitation Self limiting of fast thermal transients Protection against loss of ground and loss
of VCC Over temperature shutdown with auto
restart (thermal shutdown) Reverse battery protected (see Figure 32) Electrostatic discharge protection
Applications All types of resistive, inductive and capacitive
loads Suitable as LED driver
DescriptionThe VND5E050AJ-E and VND5E050AK-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 VND5E050AJ-E and
VND5E050AK-E are designed to drive 12V
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 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, 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. Typical value with all loads connected.
