Description
The VND5E006ASP-E is a double channel
high-side driver manufactured in the ST
proprietary VIPower™ M0-5 technology and
housed in the tiny PowerSO-16 package. The
VND5E006ASP-E is designed to drive 12 V
automotive grounded loads delivering protection,
diagnostics and easy 3 V and 5 V 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 overvoltage 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, overtemperature
indication, short-circuit to VCC diagnosis and
ON-state and 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.
