SNOU205 December 2024 LMG2650
The LMG2650 has two modes of operation controlled by the EN pin. The device is in Active mode when the EN is logic high and in Standby mode when the EN pin is logic low. See the LMG2650 650V 95mΩ GaN Half Bridge with Integrated Driver and Current Sense Emulation data sheet for more information. The LMG2650EVM-100 by default has the EN pin set high with a 0 Ohm resistor connected to 12V so the device is normally operational. By removing this resistor, the EN test point can be shorted to AGND and the device enters Standby mode.
