General Description

The device is based on Infineon’s power technology SPT which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry.

The battery voltage is regulated at a precise value between 10.6 V and 16 V.

In case of communication loss, the regulator is able to proceed with the voltage regulation by using adjustable default values.

Overview
