DESCRIPTION
The TPS2480/81 are designed to minimize inrush into applications and protect both the load and the FET from over-current or short circuit events. They control an external N-channel MOSFET switch and provide accurate voltage, current, and power monitoring using a configurable 12 bit A/D converter via an I2C interface. The independently adjustable power limit and current limit ensure that the external MOSFET operates within the FET's Safe Operating Area (SOA).
The flexible design includes a Power Good output which can be used for sequencing as well as load fault indication. An external timer capacitor can set the fault...
