TPS2480PWR

正电压智能保护装置热插拔控制器和I2C电流监视器 Positive Voltage Intelligent Protection Device Hotswap Controller and I2C Current Monitor

DESCRIPON

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.
