TECHNICAL DATA
Automotive 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 Vbat 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.
