Intelligent power switch

Texas Instruments' TPIC2404 is a monolithic, high-voltage, high-current, quadruple switch especially designed for driving peripheral loads, such as relays, solenoids, motors, lamps, and other high-voltage, high-current loads frorn low-level logic. It can switch currents of up to 1 A without any problem; the current may be increased to 4 A by connecting four outputs in parallel. The outputs are of the open-collector type.
