Description
The VND5E025AY-E is a double-channel
high-side driver manufactured using
STMicroelectronics^® proprietary VIPower^®
M0-5 technology and housed in PowerSSO-36
package. The VND5E025AY-E is designed to
drive 12 V automotive grounded loads, and to
provide protection and diagnostics. It also
implements a 3 V and 5 V CMOS-compatible
interface for use 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 providing
enhanced diagnostic functions including fast
detection of overload and short-circuit to ground
through power limitation indication,
overtemperature indication, short-circuit to V_CC
diagnosis.
The current sensing and diagnostic feedback of
the whole device can be disabled by pulling the
CS_DIS pin high to share the external sense
resistor with similar devices.
