Product Description

Interval and Wipe/ Wash Wiper Control IC


The LD33197 (analog 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 LD33197 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 LD33197 is built using bipolar technology and parametrically specified over the automotive ambient temperature range and 8.0 to 16 V supply voltage. The LD33197 can operate in both front and rear wiper applications.
