Description

The VND5E025AS-E is a double channel high-

side driver manufactured using ST proprietary

VIPower^®M0-5 technology and housed in

SO-16L 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.

– Compliant with European directive

2002/95/EC

– Very low current sense leakage

■

Diagnostic functions

– Proportional load current sense

– High current sense precision for wide

currents range

– Current sense disable

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_CCdiagnosis 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.

– Off-state open- load detection

– Output short to V_CCdetection

– 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 V_CC
