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

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.
