Description

The VNQ5E250AJ-E is a quad channel high-side

driver manufactured using ST proprietary

VIPower™ M0-5 technology and housed in

PowerSSO-16 package. The device 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 the 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

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 share

the external sense resistor with similar devices.
