U2640B Product details

Description

With the U264xB, Atmel Wireless & Microcontrollers developed a family of intermittent- and wipe/wash control circuits for windshield or backlite wiper systems with identical basic functions.

The circuit design provides the possibility to generate ”x” versions using different metallization masks.

Features

D Relay activation can be controlled by a limit switch of the wiper motor or by a fixed activation period for systems without limit switch D Debounced input stages D Enable/disable of pre-wash delay by program pin D Polarity of WIWA: VBatt D Polarity of INT: VBatt D Relay output is protected with a clamping diode D Relay activation: D Interval pause: D After wiping: D Pre-wash delay: 0.48 s 5.8 s 5.2 s 0.52 s D Wipe/wash mode with priority D Protected in accordance to ISO/TR 7637.
1 D EM.
