Diodes Incorporated has announced the DGD2136 fully integrated 3-phase gate driver IC, intended for driving N-channel MOSFETs or IGBTs in a half-bridge configuration. With its floating high-side drivers, bootstrap operation allows the DGD2136 to switch up to 600 V, while standard logic level inputs down to 2,4 V enable an easy control interface. This gate driver is designed for BLDC and PMSM motor drive applications such as power and garden tools, air conditioners, sewing machines, industrial motors and others. The increased use of BLDC and PMSM motors reflects industry directives to improve the efficiency of electrical motors and achieve the goal of zero maintenance and minimise the total cost of ownership. To meet this requirement, the DGD2136 is optimised for 3-phase applications, driving three half-bridges formed from N-channel MOSFETs or IGBTs. A high voltage process enables the floating high-side drivers to operate up to 600 V while the driver outputs feature high-pulse current buffers to minimise driver cross conduction.
