    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) DESCRIPTION The AllegroTM A1369 is a customer programmable, high accuracy linear Hall effect-based current sensor IC. It is packaged in a thin 3-pin SIP package 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. The device features One-TimeProgramming (OTP), using non-volatile memory, to optimize device sensitivity and the quiescent output voltage (QVO) (output with no magnetic field) for a given application or circuit. The A1369 also allow for optimized performance over temperature through programming the temperature coefficient for both Sensitivity and QVO at Allegro end of line test. These ratiometric Hall effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The quiescent voltage output is user adjustable around 50% of the supply voltage and the output sensitivity is programmable within a range of 8.5 mV/G to 12.5 mV/G for the A1369-10 and 22 mV/G to 26 mV/G for the A1369-24.
