Geehy New product introduction – GHD3440 Motor Dedicated Gate Driver
Geehy are glad to announce the release of the below product:
GHD3440 Motor Dedicated Gate Driver 200V Dual N-channel Three-Phase Driver, Compatible with 3.3V/5V Logic Input.
GHD3440 is a three-phase medium-voltage high-speed gate drive IC, which is specially designed for driving double-N-channel VDMOS power transistor or IGBT in bridge circuits, and is suitable for application schemes for battery-
powered DC brushless motors. The embedded typical dead time is 250ns.
When the dead time of the MCU output signal is less than the embedded dead time, the actual dead time is the embedded dead time. On the contrary, when the dead time of the MCU output signal is greater than the embedded dead time, the actual dead time is the output dead time of MCU. The embedded VCC and VBS under voltage protection functions can prevent the system from turning on the external power transistors at low driving voltage. The output of the high-side driving circuit and the output of the low-side driving circuit are controlled through input signals.
Various tools based on DC brushless motors in battery-powered systems
Electric tools, such as electric wrenches, electric screwdrivers, electric drills, and electric hammers
Garden tools, such as lawn mowers, pruners, hedge trimmers, and chain saws
Cleaning tools, such as electric cleaning brushes and vacuum cleaners
