Technical Data

This document contains certain information on a new product.

Specifications and information herein are subject to change without notice.

Integrated Quad Half-Bridge,

Triple High-Side and EC Glass

Driver with Embedded MCU and

LIN for High End Mirror

includes a high-performance HC08 microcontroller with a

SMARTMOS

a timer, enhanced serial communications interface (ESCI), an

analog-to-digital converter (ADC), serial peripheral interface (SPI)

(only internal), and an internal clock generator module. The analog

control die provides four half-bridge and three high-side outputs with

diagnostic functions, an EC glass driver circuit, a Hall-Effect sensor

input, analog inputs, voltage regulator, window watchdog, and local

interconnect network (LIN) physical layer.

application performance adjustments and space-saving PCB design.

It is well suited for the control of automotive high-end mirrors.
