Diodes Incorporated recently announced the DGD2136, a fully integrated three-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 chip 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 those commonly found in household appliances, power and garden tools, air conditioners, sewing machines and industrial motors.
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 in order to minimise the total cost of ownership. To meet this requirement, the DGD2136 is optimised for three-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.
The device incorporates multiple protections: over-current is sensed via an external resistor to turn off all outputs; matched propagation delays with an internal deadtime and shoot-through logic prevent both outputs from being high when both inputs are high (a fault state); a VCC under-voltage lockout shuts down the respective high side output; and built-in immunity to high dv/dt transients at the VS pin minimises the risk of false triggering. The DGD2136 also has a fault signal output that enables monitoring of the driver stage and can be used with the RC input pin to provide an adjustable reset time.
The DGD2136 gate driver is offered in an industry-standard SO-28 package.
