Abstract
An integrated circuit provides a load with back-flow and open-circuit protection and includes a load, a trigger circuit, and a shunt circuit. The integrated circuit provides large-size LED displays having series LED connection with back-flow and open-circuit protection. The shunt circuit of the integrated circuit shunts the back-flow current from the LED when an ESD is applied, and offers an alternative current path when an LED fails so that other functioning LEDs can still emit light.
