TLE 8203E – New Driver IC for Mirror Adjustment, Mirror Heating and Light Control

TLE 8203E block diagram

TLE 8203E is an application-specific standard product (ASSP) for automotive mirror control applications. It includes the power stages necessary to drive mirror loads such as mirror position, mirror defrost and 5W or 10W lamp or LED, i.e. turn signal. It is a monolithic die based on Infineon’s smart mixed technology SPT which combines bipolar and CMOS control circuitry with DMOS power devices.

The short circuit and overtemperature protection and detailed diagnosis of this product meet automotive application safety requirements. The current sense output improves system reliability and performance. The standard SPI interface saves microcontroller I/O lines while still providing flexible control of the power stages and detailed diagnosis.

Open load diagnosis for all outputs All outputs with shortcircuit protection and diagnosis Overtemperature protection with pre-warning Green product (RoHS complaint) with qualification according to AEC Very low current consumption in sleep mode (<6µA) Current sense analog output with multiplexer
