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 3V 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

Features and Benefits

 Inductive load driver capable of driving 3 to 6V DC coils

 Optimized to switch inductive loads from supply of 3 to 5V with

the capability to drive coils up to 2.5W from a 5V rail

 Fully integrated into a single SOT23 or dual SOT26 package to

minimize footprint area and reduce number of components

 Includes Zener across output to reduce EMI noise

 Internal low saturation BJT to reduce power dissipation in driving

high currents into the coil

 Output guaranteed to be in off-state condition during no input

 Near – Zero quiescent supply current in off-state condition with

minimal leakage

 Rugged design and inherently robust by using solid-state BJT

technology integrated into a single die
