Advance Information
Automotive Wash Wiper Timer
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 MC33197A 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
MC33197A is built using bipolar technology and parametrically specified
over the automotive ambient temperature range and 8.0 to 16 V supply
voltage. The MC33197A can operate in both front and rear wiper
applications.
