high PWM duty cycle. In these cases, superior performances can be achieved by using an external bootstrap diode
in parallel with the internal bootstrap network.
Bootstrap Power Supply Design
For information related to the design of the bootstrap power supply while using the integrated bootstrap functionality
of the IRS26310, please refer to Application Note 1123 (AN-1123) entitled “Bootstrap Network Analysis: Focusing on
the Integrated Bootstrap Functionality.” This application note is available at www.irf.com.
For information related to the design of a standard bootstrap power supply (i.e., using an external discrete diode)
please refer to Design Tip 04-4 (DT04-4) entitled “Using Monolithic High Voltage Gate Drivers.” This design tip is
available at www.irf.com.
Separate Logic and Power Grounds
The IRS26310D has separate logic and power ground pin (V
noise problems that can occur in power conversion applications. Current sensing shunts are commonly used in
many applications for power inverter protection (i.e., over-current protection), and in the case of motor drive
applications, for motor current measurements. In these situations, it is often beneficial to separate the logic and
power grounds.
