URYD21 Datasheet
  

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
