        300mA BI-DIRECTION RELAY DRIVER

         

         

         

        DESCRIPTION

                        

        URYD21 is a bi-direction relay driver circuit, used to

        control the magnetic latching relay, with large output

        capability, 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.

          

        FEATURES

         

        *  Supports USB DCP Shorting D+ Line to5 to 36V input voltage range

        *  Low Power Consumption (IQ<1uA) 

        *  Input High Level Threshold: 3V, compatible with

        *  most single chip microcontroller 

        *  Typical Driving Current: 300mA  

        *  Rds(on)=15ohm(Vin=12V, PMOSFET+NMOSFET)

        *  Rds(on)=10ohm(Vin=20V, PMOSFET+NMOSFET)

        *  Peak Driving Current: 500mA@Vin=24V  

        *  Environment Temperature: -40°C~85°C
