ST两速脉冲雨刷控制解决方案(2)

Two Speed Pulse Wiper CONTROL (2)

Today’s windshield wiper systems require high reliability electronic COMPONENTS to ensure safe and proper operation under all conditions. Most modern systems offer intermittent as well as variable speed operation, with more ADVANCED systems offering moisture detection to regulate the degree of windshield wiping action. From BRIDGE and high-side drivers to low cost, high performance microcontrollers, coupled with an extensive STANDARD product offering, ST has a broad range of solutions to choose from.
