ZH639D0

Three-Phase Gate Driver

100V Three-Phase, Half-Bridge Gate

The ZH639D0 is a low-voltage, high-speed three-phase half-bridge gate driver for power MOSFETs (N-channel) and IGBTs. It integrates three high-side and low-side Schmitt trigger inputs, along with three output channels featuring internal adaptive dead-time control to prevent cross-conduction.The output module incorporates balanced pull-up/pull-down circuits, eliminating the need for series resistor-diodes between the system and power transistor gates. High-side and low-side outputs are independently controlled by the input, with under-voltage protection enabled on the high-side.
