The MDC3105LT1G is an Inductive Load Driver intended to replace an array of three to six discrete components with an integrated SMT part. It can be used to switch 3 to 6VDC inductive loads such as relays, solenoids, incandescent lamps and small DC motors without the need of a free-wheeling diode.
● Provides a robust driver interface between DC relay coil and sensitive logic circuits
● Optimized to switch relays from a 3 to 5V rail
● Capable of driving relay coils rated up to 2.5W at 5V
● Low input drive current and good back-to-front transient isolation
● Internal Zener eliminates need for free-wheeling diode
● Internal Zener clamp routes induced current to ground for quieter system operation
● Guaranteed OFF-state with no input connection
● Supports large systems with minimal OFF-state leakage
● ESD resistant in accordance with the class 1C human body model
● Low sat voltage reduces system current drain by allowing use of higher resistance relay coils
