Figure 22: Current conduction path between VCC and VB pin
Relevant Application Situations:
The above mentioned bias condition may be encountered under the following situations:
?
?
In a motor control application, a permanent magnet motor naturally rotating while VCC power is OFF. In
this condition, Back EMF is generated at a motor terminal which causes high voltage bias on VS nodes
resulting unwanted current flow to VCC.
Potential situations in other applications where VS/VB node voltage potential increases before the VCC
voltage is available (for example due to sequencing delays in SMPS supplying VCC bias)
Application Workaround:
Insertion of a standard p-n junction diode between VCC pin of IC and positive terminal of VCC capacitors (as
illustrated in Fig.23) prevents current conduction “out-of” VCC pin of gate driver IC. It is important not to connect the
VCC capacitor directly to pin of IC. Diode selection is based on 25V rating or above & current capability aligned to
ICC consumption of IC - 100mA should cover most application situations. As an example, Part number # LL4154
from Diodes Inc (25V/150mA standard diode) can be used.

Note that the forward voltage drop on the diode (VF) must be taken into account when biasing the VCC pin of the IC
to meet UVLO requirements. VCC pin Bias = VCC Supply Voltage – VF of Diode.
