Product Description

The MP6211-3/MP6212-3 single-channel Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP6211-3/MP6212-3 Analog switch has 95mΩ on-resistance and operates from 2.7V to 5.5V input. It is available with guaranteed current limits, making it ideal for load switching applications. The MP6211-3/MP6212-3 has built-in protection for both over current and increased thermal stress. For over current, the device will limit the current by changing to a constant current mode. As the temperature increases as a result of short circuit, the device will shut off. The device will recover once the device temperature reduces to approx 120°C. The FLAG output of MP6211-3/MP6212-3 will report a fail mode (low level) when over current or over temperature is encountered. The FLAG will not change state when the input UVLO is triggered. The MP6211-3/MP6212-3 is available in 8-Pin MSOP with exposed pad, SOIC8 with exposed pad, and TSOT23-5 packages.
