Integrated Relay Driver from Diodes Incorporated Optimizes Inductive Load Control
By integrating a complete solid-state relay driver into a single, surface-mount package, DRDC3105 from Diodes Incorporated minimizes the PCB footprint, reduces the component count and improves the reliability of inductive load control circuits. Providing a rugged interface between standard logic and 3V to 6V DC inductive loads, the relay driver is designed to handle relays, solenoids, incandescent lamps and small motors in a wide range of applications. From a 5V supply rail, DRDC3105 has the capability to drive coils rated at up to 2.5W.The
Integrating robust pre-biased transistor technology delivering high transient isolation between input and output, DRDC3105 will protect sensitive input circuitry and guarantee to put its output into a safe off-state condition when the input is lost or disconnected. The bipolar’s low saturation characteristic means the device will drive current up to 0.5A through the coil when on and achieve near-zero current consumption in the off-state.
In 10k quantities, the DRDC3105 relay driver is priced at $0.09 USD each for the single driver package and $0.15 USD each for the dual driver package.
