IL33197
A
UTOMOTIVE WASH WIPER TIMER
The IL33197A is a standard wiper timer control device designed for harsh automotive applications. The
device can perform the intermittent, after wash, and continuous wiper timer functions. It is designed to
directly drive a wiper motor relay. The IL33197A requires very few external components for full system
implementation. The intermittent control pin can be switched to ground or V
bat
to meet a large variety of
possible applications. The intermittent timing can be fixed or adjustable via an external resistor. The
IL33197A is built using bipolar technology and parametrically specified over the automotive ambient
temperature range and 8.0 to 16 V supply voltage. The IL33197A can operate in both front and rear wiper
applications.
