A1369

A1369 Customer Programmable Linear Hall-Effect Sensor Optimized for Use in Current Sensing Applications FEATURES AND BENEFITS Customer programmable offset, and sensitivity Sensitivity & QVO temperature coefficients programmed at Allegro for improved accuracy Output value decreases with South Magnetic Field and increases with North Magnetic field. 3-pin SIP package for easy integration with magnetic concentrator Low noise, moderate bandwidth, analog output High speed chopping scheme minimizes QVO drift over temperature Temperature-stable quiescent voltage output and sensitivity Precise recoverability after temperature cycling Output voltage clamps provide short circuit diagnostic capabilities Under voltage lock-out (UVLO) Continued on the next page… Package: 3-Pin SIP (suffix UA) Not to scale DESCRIPTION The Allegro™ A1369 is a customer programmable, high accuracy linear Hall effect-based current sensor IC. It is packaged in a thin 3-pin SIPpackage to allow for easy integration with a magnetic core to create a highly accurate current sensing module. The programmable nature of the A1369 enables it to account for manufacturing tolerances in the final current sensing module assembly. This temperature-stable device is available in a through-hole single in-line package (TO-92). The accuracy of the device is enhanced via programmability on the output pin for endof-line optimization without the added complexity and cost of a fully programmable device. ...
