Door Control Module

Key Products
Door modules, in their simplest form, need to be able to reliably control standard loads such as those presented by door locking motors. In more complex door zone systems, the chipset needs to not only control multiple standard loads such as door lock motors, mirror folders and levellers, but also those for defrosters and several lighting functions from LEDs to incandescent bulbs. Solutions need to be both flexible and scalable, to satisfy the need for different door electronic variants from basic to premium.

Flexible, scalable solutions

ST offers “Door Zone System ICs” integrating a power management block, CAN and LIN transceivers and drivers/actuators for additional loads, all in one single package. Other solutions are also available, such as an integrated two-chip solution tailored for different door variants, a range of 5V regulators with varying current loads, and High and Low-Side drivers in VIPower™ technology. 

ESD and battery protection devices complement the offer, to cover all design requirements.
