The LM7311x family is a highly integrated, circuit-protection and power-management device in a small package. The devices provide multiple protection modes that use few external components and are a robust defense against overloads, short-circuits, voltage surges and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the devices designed for power MUX and ORing applications, as well as systems that need load side energy hold up storage if input power supply fails. The devices use a linear ORing based scheme to maintain almost zero DC reverse current and emulate ideal diode behavior with minimum forward voltage drop and power dissipation.

Output slew rate and inrush current can be adjusted using a single external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if input exceeds an adjustable overvoltage threshold.

The devices are available in a 3mm × 3mm, for improved thermal performance and reduced system footprint.

The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
