DRDC3105
INTEGRATED RELAY, INDUCTIVE LOAD DRIVER
Description and Applications
The DRDC3105 is an integrated solid-state DC relay driver that can
switch inductive loads. It provides a robust driver interface by acting as
a buffer stage between sensitive logic circuits and that of 3 to 6V DC
inductive relay coils. With a low input drive current requirement, the
DRDC3105 only has slight loading on the input circuitry and it will
provide good transient isolation between output and input channels.
The output switch is guaranteed by design to go open-circuit and fall
into the off-state condition when input drive is lost or disconnected.
In the industry standard SOT23 and SOT26, the DRDC3105 comes as
a single or dual die which can replace three to six individual discrete
components within a single integrated package, including a Zener
across the output. The Zener will clamp at 6.6V to sink inductive
currents to ground which will reduce EMI noise in the system. By
integrating the Zener, the DRDC3105 eliminates the need for an
external free-wheeling diode and allows the driving of inductive loads
such as relays, solenoids, incandescent lamps, and small DC motors in:
• Automotive: 5.0 V Driven Relays, Lamp Drivers, Motor Controls
• Telecom equipment: Modems, DSL, Cable (EMTA), Line Cards,
IP-PBX, Analog Terminal Adaptors, End User Telecom Equipment
• Desktop Computers, Printers, Photocopiers
• LCD & Plasma TVs, Set Top Boxes
• Consumer Appliances, White Goods, Automated Door Control
• Industrial equipment inc. Process Control, ATE equipment
• Solar inverters
