IL33197

1

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

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.
