2.1.3 Enable Pin

The LMG2652 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 LMG2652 650V 140mΩ GaN Half Bridge with Integrated Driver and Current Sense Emulation data sheet for more information. The LMG2652EVM-101 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.
