MP6219 5V, 1A – 2A Programmable Current Limit Power Distribution Switch SOICE

MP6219 5V, 1A – 2A Programmable Current Limit Power Distribution Switch SOICE

The MP6219 is a protection device designed to protect circuitry on the output from transients on input.

Key Specifications

Features

• Integrated 44mΩ FET
• Adjustable Current Limit to 2A
• Optimized for 5V Inputs
• Enable Active High
• 1.1ms Soft-Start Rise Time

Typical Application Circuit

Applications

• USB Power Distribution
• PCI Bus Power
• Notebook PC
• Inrush Current Limit
• Heavy Capacitive Loads

Design Notes

• Check the input common-mode range against the actual signal, especially in single-supply rails where ground-referenced signals sit at the edge.
• Capacitive load drives stability; add series isolation when driving cables or ADC inputs directly.
• Offset voltage and its drift, not gain bandwidth, usually set the achievable accuracy in DC instrumentation.
• Decouple at the pin with the smallest package capacitor that meets the transient requirement, returned to a local ground.
