Integrated Bootstrap Functionality
The new IRS233(0,2)D family features integrated high-voltage bootstrap MOSFETs that eliminate the need of the external
bootstrap diodes and resistors in many applications.
There is one bootstrap MOSFET for each high-side output channel and it is connected between the V
respective floating supply (i.e., V
The integrated bootstrap MOSFET is turned on only during the time when LO is ‘high’, and it has a limited source current due
to R
drain-source (collector-emitter) drop of the external IGBT (or MOSFET), and the low-side free-wheeling diode drop.
The bootstrap MOSFET of each channel follows the state of the respective low-side output stage (i.e., the bootstrap MOSFET
is ON when LO is high, it is OFF when LO is low), unless the V
case, the bootstrap MOSFET is designed to remain off until V
