Description
The VND5E025AK-E is a double channel highside driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
PowerSSO-24 package. The VND5E025AK-E is
designed to drive 12 V automotive grounded
loads delivering protection, diagnostics and an
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.

GND protection network against reverse battery
This section provides two solutions for implementing a ground protection network against
reverse battery.
3.1.1
Solution 1: resistor in the ground line (RGND only)
This can be used with any type of load.
The following is an indication on how to dimension the RGND resistor.
1.
RGND ≤ 600mV / (IS(on)max)
2.
RGND ≥ (−VCC) / (-IGND)
where -IGND is the DC reverse ground pin current and can be found in the absolute
maximum rating section of the device datasheet.
Power dissipation in RGND (when VCC VOL max = 4V
For the values of VOLmin,VOLmax, IL(off2)r and IL(off2)f see Table 10: Open-load detection
(8 V < VCC < 18 V).
