DGD21844S14-13

DGD21844 PART OBSOLETE - USE DGD21844M OBSOLETE – PART DISCONTINUED HALF- BRIDGE GATE DRIVER IN SO-14 Description Features The DGD21844 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 DGD21844’s high-side to switch to 600V in a bootstrap operation. • • The DGD21844 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) for easy interfacing with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. Programmable Deadtime, by an external resistor, provides more system level flexibility. The DGD21844 is offered in SO-14 package, the operating temperature extends from -40°C to +125°C. • • • • • • • • • • • • Applications • • • • • DC-DC Converters DC-AC Inverters AC-DC Power Supplies Motor Controls Class D Power Amplifiers Floating High-side Driver in Bootstrap Operation to 600V Drives Two N-Channel MOSFETs or IGBTs in Half Bridge Configuration 1.4A Source / 1.8A Sink Output Current Capability Outputs Tolerant to Negative Transients Programmable Dead Time to Protect MOSFETs Wide Low-side Gate Driver and Logic Supply: 10V to 20V Wide Logic Supply Voltage Offset Voltage:-5V to 5V Logic Input (IN and SD*) 3.3V Capability Schmitt Triggered Logic Inputs with Internal Pull Down Undervoltage Lockout for High and Low Side Drivers Extended Temperature Range: -40°C to +125°C Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ Mechanical Data • • • • • • Case: SO-14 (Type TH) Case material: Molded Plastic. “Green” Molding Compound.
