Description
The DGD1503 is a high-voltage / high-speed gate driver capable of driving N-channel MOSFETs and IGBTs in a half-bridge configuration. High voltage processing techniques enable the DGD1503’s high side to switch to 250V in a bootstrap operation.
The DGD1503 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver output features high pulse current buffers designed for minimum driver cross conduction. DGD1503 has a fixed internal deadtime of 430ns (typical).
The DGD1503 is offered in the SO-8 (Type TH) package and operates over an extended -40°C to +125°C temperature range.
