SC310 General Description
The SC310 is a high-side current sense amplifier ideal for any application where precision current monitoring is needed. Possible uses include battery-powered products such as cellphones and notebooks, as well as industrial and data acquisition applications. The wide 2.7V to 25V common mode input range is independent of supply range, providing complete flexibility in battery sensing applications.
The Current-Sense Amplifier offers three gain versions, SC310A (gain 20 V/V), SC310B (gain 50 V/V) and SC310C (gain 100 V/V). An external shutdown pin (SHDN) enables turn off for the IC. A buffered output with low impedance renders the overall gain immune to load resistance. Output range is from 0V to Vcc - 1.7V. Other features include tiny SOT-23-6 packaging, very low supply current, and wide supply voltage range (3V to 25V).
The SC310 is rated for operation over the Industrial Temperature range (-40°C to +125°C).
