WXNSIC XJNG0461

XJNG0461 is a three-phase high-speed power MOSFET driver with 6 channels and a maximum operating voltage of 40V. Fabricated using a high-voltage compatible process, the device integrates both high-side and low-side gate drive circuits on a single chip, with each phase featuring two input signals and two output signals for both the high-side and low-side. The logic inputs are compatible with standard CMOS or LSTTL levels, with input logic levels as low as 3.3V. The device provides a 10V gate-to-source voltage for both PMOS and NMOS, and incorporates a built-in dead-time function to prevent shoot-through between the high-side and low-side PMOS and NMOS within the same phase. To simplify PCB design, the XJNG0461 integrates a 5V/40mA LDO that can be used to supply power to an MCU or other devices. In addition, a thermal shutdown protection function is integrated for safety purposes.
