DGD21814S14-13

Gate Driver Overview

The DGD21814S14-13 is a high-voltage, high-speed gate driver designed for driving N-channel MOSFETs and IGBTs in half-bridge configurations. It features a floating high-side driver capable of bootstrap operation up to 600V. The device provides independent high-side and low-side outputs with peak source and sink currents of 1.9A and 2.3A, respectively. Logic inputs are compatible with standard TTL and CMOS levels down to 3.3V. Operating supply voltage ranges from 10V to 20V. Typical rise and fall times are 40ns and 20ns. Maximum turn-on and turn-off delays are 270ns and 330ns. The component operates within a temperature range of -40°C to +125°C and is housed in a 14-SOIC package.

Gate Driver Procurement Notes

Verify the specific suffix 'S14-13' against official Diodes Incorporated documentation to confirm the SOIC-14 package type and tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range and logic voltage levels before integration. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance with RoHS standards.

Gate Driver Selection Notes

Select this component when a robust half-bridge driver with 600V high-side capability is required. The wide supply voltage range and 3.3V logic compatibility facilitate interfacing with various control ICs. Consider the thermal performance and package size constraints relative to the intended power dissipation and PCB layout requirements for optimal system design.

Gate Driver Part Context

This part belongs to the DGD21814 series of high-voltage gate drivers manufactured by Diodes Incorporated. The series is engineered for industrial and consumer applications requiring efficient power switching. The S14-13 designation specifically identifies the surface-mount variant in the SOIC-14 package, distinguishing it from other form factors or leaded versions within the same functional family.

Gate Driver Replacement Considerations

Direct substitutes include the generic DGD21814M or DGD21814MS14-13, provided pinout and electrical specifications match exactly. Verify that alternative packages maintain identical thermal characteristics and footprint dimensions to ensure seamless board replacement without redesign.
