A1386

A1386 5 V Field-Programmable Linear Hall Effect Sensor IC with 3 V Supply Functionality, Analog Output, and Miniature Package Options Features and Benefits Low power consumption using 3 V supply Factory programmed sensitivity temperature coefficient (0.13%/°C nominal) Programmability at end-of-line Ratiometric sensitivity, quiescent voltage output, and clamps for interfacing with application DAC Temperature-stable quiescent voltage output and sensitivity Precise recoverability after temperature cycling Output voltage clamps provide short circuit diagnostic capabilities Wide ambient temperature range: –40°C to 150°C Resistant to mechanical stress Miniature package options Packages 3-pin ultramini SIP 1.5 mm × 4 mm × 3 mm (suffix UA) Description The Allegro® A1386 programmable, linear, Hall effect sensor IC is designed for low power, high accuracy, and small package size applications. The accuracy of this device is enhanced via programmability on the output pin for end-of-line optimization without the added complexity and cost of a fully programmable device. The A1386 has two operating modes, normal and low power. In normal operation mode the A1386 operates much like its predecessors, theA1381,A1382,A1383, andA1384, as a highly accurate, user-programmable linear sensor IC with a ratiometric output. In low power mode, the device actually disengages some internal components in order to reduce power consumption. Although the accuracy of the device is substant...
