FEATURES
DESCRIPTION
Programmable FET Power Limit
The TPS2480/81 are designed to minimize inrush into
applications and protect both the load and the FET
External N-Channel FET Gate Drive
from over-current or short circuit events. They control
Programmable Fault Timer
an external N-channel MOSFET switch and provide
Open Drain Power Good Output
accurate voltage, current, and power monitoring using
I2C monitoring of Current, Voltage and Power
a configurable 12 bit A/D converter via an I2C
interface. The independently adjustable power limit
High Accuracy Current Monitoring
and current limit ensure that the external MOSFET
(1% over temperature)
operates within the FET's Safe Operating Area
Dynamic Calibration
(SOA).
9-V to 26-V Input Range
The flexible design includes a Power Good output
which can be used for sequencing as well as load

the fault time to help immunize the system from
nuisance shutdowns during brief transient events.
Hard Drives
Storage Networks
The monitoring circuitry incorporates a high accuracy
Base Stations
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
readings to the needs of the application. An additional
multiplying register calculates power in Watts. The
I2C interface uses multi-level addressing to allow up
to 16 programmable addresses.
