The MDC3105LT1 from On Semiconductor is an integrated circuit designed to efficiently drive inductive loads such as relays, solenoids, and small DC motors. It replaces multiple discrete components with a single SMT package, specifically the SOT-23-3.
This device is optimized for switching relays from a 3.0 V to 5.0 V rail and can handle relay coils rated up to 2.5 W at 5.0 V. It features a robust driver interface between DC relay coils and sensitive logic circuits, with an internal Zener clamp that eliminates the need for a free-wheeling diode and routes induced current to ground for quieter system operation.
Key electrical specifications include a maximum output sink current of 500mA and a load voltage capability of up to 6V. The operating ambient temperature range is -40°C to +85°C. The device is supplied in a surface-mount SOT-23-3 (TO-236) package.
Applications for the MDC3105LT1 include telecom equipment, computer peripherals, consumer electronics, industrial controls, and automotive systems requiring reliable inductive load switching.
