![]() | Overview of PT5639: The PT5639 is a high speed power MOSFET and IGBT driver with three independent high and low side referenced output channels for 3-phase gate driver. Built-in deadtime protection and Shoot-through protection that prevent half-bridge against damage. The UVLO circuits prevent malfunction when VCC and VBS are lower than the specified threshold voltage. Novel high-voltage BCD process and common-mode noise canceling technique provide stable operation of high-side drivers under high-dv/dt noise circumstances and excellent negative transient voltage tolerance. PT5639 also includes a 5V/3.3V 50mA LDO, which saving the BOM cost. |
