说明

The TPS22811x is a highly integrated power distribution solution in a small package. The device allows control and monitoring of power supply rails using minimum number of external components.

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 device integrates a fast-trip response to provide protection against severe faults at the output during steady-state.

The devices provide an accurate analog sense of the output load current as well as a digital power good indication to help with system monitoring and diagnostics.

The devices are available in a 2-mm × 2-mm, 10-pin HotRod™ QFN package 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.
