URYD21数据手册UTC中文资料规格书

描述 Description

URYD21 is a bi-direction relay driver circuit, used to control the magnetic latching relay, with large outputcapability, ultra-low power consumption. It can be widely used in smart meters and other pulses, level control applications. URYD21  can  provide 300mA typical driving current, which will different according to the relay coil resistance. The input High Level Threshold of  URYD21 is 3V; it can compatible with most single chip microcontroller.
