Texas Instruments TPS2480 Datasheet
www.ti.com TPS2480 TPS2481 SLUS939B – APRIL 2010 – REVISED DECEMBER 2010 Positive Voltage Intelligent Protection Device Hotswap Controller and I2C Current Monitor Check for Samples: TPS2480, TPS2481 FEATURES 1 • Programmable FET Power Limit • External N-Channel FET Gate Drive • Programmable Fault Timer • Open Drain Power Good Output • I2C monitoring of Current, Voltage and Power • High Accuracy Current Monitoring (1% over temperature) • Dynamic Calibration • 9-V to 26-V Input Range APPLICATIONS • Servers • Hard Drives • Storage Networks • Base Stations 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 time to help immunize the system from nuisance shutdowns during brief transient events. The monitoring circuitry incorporates a high accuracy A/D converter which can be configured from a 9 to 13 bit converter. The internal gain of the A/D can be configured to scale the current, voltage and power read.
