Advance Information
Automotive Wash Wiper Timer
The MC33197 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 MC33197 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
MC33197 is built using bipolar technology and parametrically specified over
the automotive ambient temperature range and 8.0 to 16 V supply voltage.
The MC33197 can operate in both front and rear wiper applications.
• Adjustable Time Interval of Less Than 500 ms to More Than 30 s
• Intermittent Control Pin Can Be Switched to Ground or Vbat
• Adjustable After Wipe Time
• Priority to Continuous Wipe
• Minimum Number of Timing Components
• Integrated Relay Driver With Free Wheeling Protection Diode
• Operating Voltage Range From 8.0 to 16 V
• For Front Wiper and Rear Wiper Window Applications
