A Product Line of Diodes Incorporated DRDC3105 INTEGRATED RELAY, INDUCTIVE LOAD DRIVER Description and Applications Mechanical Data The DRDC3105 is an integrated solid-state DC relay driver that can Case: SOT23 & SOT26 switch inductive loads. It provides a robust driver interface by acting as Case Material: Green Plastic Molding Compound a buffer stage between sensitive logic circuits and that of 3V to 6V DC UL Flammability Rating 94V-0 inductive relay coils. With a low input drive current requirement, the Moisture Sensitivity: Level 1 per J-STD-020 DRDC3105 only has slight loading on the input circuitry and it will Terminals: Finish Matte Tin Plated Leads, Solderable per provide good transient isolation between output and input channels. MIL-STD-202, Method 208 The output switch is guaranteed by design to go open-circuit and fall Weight: SOT23 = 0.008 grams (Approximate) into the off-state condition when input drive is lost or disconnected. SOT26 = 0.018 grams (Approximate) In the industry standard SOT23 and SOT26, the DRDC3105 comes as Features and Benefits a single or dual die which can replace three to six individual discrete Inductive load driver capable of driving 3 to 6V DC coils components within a single integrated package, including a Zener Optimized to switch inductive loads from supply of 3 to 5V with across the output. The Zener will clamp at 6.6V to sink inductive the capability to drive coils up to 2.5W from a 5V rail currents to ground which will reduce EMI noise in the system. By Fully integrated into a single SOT23 or dual SOT26 package to integrating the Zener, the DRDC3105 eliminates the need for an minimize footprint area and reduce number of components external free-wheeling diode and allows the driving of inductive loads Includes zener across output to reduce EMI noise such as relays, solenoids, incandescent lamps, and small DC motors in: Internal low saturation BJT to reduce power dissipation in driving high currents into the coil Automotive: 5.0V Driven Relays, Lamp Drivers, Motor Controls Output guaranteed to be in off-state condition during no input Telecom Equipment: Modems, DSL, Cable (EMTA), Line Cards, Near-Zero quiescent supply current in off-state condition with IP-PBX, Analog Terminal Adaptors, End-User Telecom Equipment minimal leakage Desktop Computers, Printers, Photocopiers Rugged design and inherently robust by using solid-state BJT LCD & Plasma TVs, Set-Top Boxes technology integrated into a single die Consumer Appliances, White Goods, Automated Door Control ESD Protected up to 1kV on Human Body Model (HBM) Industrial Equipment including Process Control, ATE Equipment Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Solar Inverters Halogen and Antimony Free.Gree Device (Note 3) Qualified to AEC-Q101 Standards for High Reliability SOT26 SOT23 SOT23 SOT26 OUT1 GND1 GND IN2 IN1 OUT ESD PROTECTED OUT2 GND2 IN HBM TO 1kV Top View Top View Top View Top View Pin-Out Pin-Out Ordering Information (Note 4) Product Package Marking Reel size (inches) Tape width (mm) Quantity per reel DRDC3105F-7 SOT23 1R6 7 8 3,000 DRDC3105E6-7 SOT26 3105 7 8 3,000 Notes: 1.
