Features

■ General

– Inrush current active management by

power limitation

– Very low stand-by current

– 3.0 V CMOS compatible inputs

– Optimized electromagnetic emissions

– Very low electromagnetic susceptibility

– In compliance with the 2002/95/EC

european directive

– Very low current sense leakage

■ Diagnostic functions

– Proportional load current sense

– High current sense precision for wide

currents range

– Current sense disable

– Off state openload detection

– Output short to Vcc detection

– Thermal shutdown indication

– Overload and short to ground (power

limitation) indication

■ Protections

– Undervoltage shutdown

– Overvoltage clamp

– Load current limitation

– Self limiting of fast thermal transients

– Protection against loss of ground and loss

of VCC

– Over-temperature shutdown with

autorestart (thermal shutdown)

– Reverse battery protected (see Figure 32)

– Electrostatic discharge protection
