Functional Description
3.3.1 Active Shut Down
The Active Shut Down feature ensures MOSFET off-state under all circumstances even if the output side supply
is inactive. The p-channel MOSFET gate is held actively high until VREG is passing the output UVLO thresholds of
the driver.
3.3.2 Interlock between MOSFET Gate and JFET Gate
The JFET can only be switched on, if the MOSFET is on, otherwise the low voltage MOSFET will be destroyed by
overvoltage. To ensure proper operation of the cascode, the driver is monitoring the MOSFET gate voltage at
MDrv pin and the JFET gate voltage at JFDrv pin. Only if the MOSFET is on, indicated by MDrv pin having low
potential, the JFET is allowed to turn on. Similar in opposite direction, MOSFET turn off is only allowed if the JFET
is in its off state.
3.3.3 Bootstrap Start up Mode Indicator
The 1EDI30J12Cx indicates at BSEN pin that the driver has entered the bootstrap start up phase with an output
current of min 2mA to drive an opto coupler if IN signal is driven high.
