The RT1720 is an over-voltage and over-current protection circuit. It monitors a circuit’s input voltage and current with its adjustable over-voltage and over-current thresholds and drives an external N-MOSFET switch to connect the input to the output voltage only when it is safe. Its wide input voltage range makes it useful for high-voltage applications and in systems that experience large transient voltages and currents, such as automotive, telecom, and industrial applications.
