Debugging Mode
If CSIN+ pin is pulled up to VCCL voltage, IR3507Z enters into debugging mode. Both drivers are pulled low and
IOUT output is disconnected from the current share bus, which isolates this phase IC from other phases.
However, the phase timing from PHSIN to PHSOUT does not change .
Emulated Bootstrap Diode
IR3507Z integrates a PFET to emulate the bootstrap diode. If two or more top MOSFETs are to be driven at higher
switching frequency, an external bootstrap diode connected from VCCL pin to BOOST pin may be needed.
