ONSEMI MDC3105LT1G Inductive Load Driver
The MDC3105LT1G is an inductive load driver designed to replace multiple discrete components with an integrated surface-mount device. It can switch 3 to 6VDC inductive loads, such as relays, solenoids, lamps, and small DC motors, without requiring an external free-wheeling diode. The device provides a robust interface between a DC relay coil and sensitive logic circuits, optimized for relay operation from a 3 to 5V power supply. It can drive relay coils rated up to 2.5W at 5V, features low input drive current, and offers good transient suppression. An internal Zener diode eliminates the need for an external free-wheeling diode by routing induced currents to ground, ensuring quieter operation. The driver guarantees an off state with no input signal, supports large systems with minimal leakage when off, and is ESD resistant according to the Class 1C human body model. Its low saturation voltage reduces system current drain, enabling the use of higher resistance relay coils.
