概述

The TPA630 is an I²C-compatible current-shunt and power monitor that supports 16 programmable addresses or an SMBUS-compatible interface. It measures both shunt voltage drop and bus supply voltage. With programmable calibration settings, conversion times, and averaging options—along with an integrated multiplier—the device provides direct readings of current in amperes and power in watts.

The TPA630 can accurately sense current across bus voltages ranging from 0 V to 36 V. It operates from a single 2.7 V to 5.5 V supply and typically consumes just 1.1 mA. The device is designed to operate over a temperature range of –40 °C to +125 °C.
