Description

The STNRGPF02/12 embed the Inrush Current Limiter function.

STNRGPF12 features a digital inrush current control generating two PWM’s signals

in order to drives the input semi-controlled bridge.

STNRGPF02 embeds inrush current control function setting high a signal that is used

to short a resistive element.
