Geehy has officially launched the GHD3450, a 200V three-phase dual N-channel motor gate driver. With a built-in bootstrap diode and two package options, TSSOP20 and QFN24, it helps simplify the design of compact motor drive systems.

Medium-Voltage High-Speed Gate Driver IC  

Supporting a 5.5V–20V supply range, 3.3V/5V logic input compatibility, and a +200V floating offset voltage, it is well suited for a wide range of DC brushless and brushed motor applications.

High-Speed Switching Capability  

It delivers a peak source current of 2.0A @15V with a 20ns fall time under a 3.3nF load, and a peak sink current of 2.7A @15V with a 35ns rise time under a 3.3nF load, helping reduce switching losses in power devices.

Multiple Protection Mechanisms  

It supports VCC/VBS undervoltage lockout, shoot-through prevention, and a built-in minimum dead time of 220ns to help protect power devices and ensure stable operation. Integrated input/output pull-down resistors further enhance driving stability.

High-Precision Dynamic Response  

Matched propagation delay between the high-side and low-side channels helps prevent bridge shoot-through and improve system efficiency and reliability. In-phase input and output preserve PWM signal integrity for more accurate control, while strong dv/dt noise immunity improves resistance to interference.

The GHD3450 motor gate driver is suitable for applications such as power tools, garden tools, drone ESCs, and cleaning robots. Samples are now available. If you are interested in Geehy products, please scan the QR code to register.
