Using the LTM2881 as an isolated 5V power supply

Posted: 30 Mar 2010     Print Version  Bookmark and Share

Keywords:LTM2881 power supply  isolated power supply  ground to ground differentials 

The LTM 2881 is an isolated RS485 transceiver that guards against large ground-to-ground differentials. An onboard DC/DC converter provides isolated 5V power to the output.

The controlling signal DI operates relative to the VL supply, which supports voltages from 1.62V to 5.5V. In both configurations, observation of a VCC2 fault is accomplished by observing a high impedance condition on RO or DOUT. When VCC2 is greater than 2.6V, RO and DOUT are driven to the appropriate logic level based on the inputs A and B and DIN. When VCC2 is less than 2.4V, RO and DOUT are high impedance.
