A1369EUA-10-T

• Product Introduction

The Allegro™ A1369 is a user-programmable, high-accuracy, linear, Hall-effect current sensor IC.

The device is available in a low-profile 3-pin SIP package and can be easily integrated with the core, resulting in a high-precision current sensing module. With programmable performance, the A1369 eliminates manufacturing tolerances during final current sensing module assembly.

This temperature-stable device is available in a through-hole single-row in-line package (TO-92). Programmability through the output pins improves device accuracy and enables end-of-production optimization without the added complexity and cost of a fully programmed device. The device uses non-volatile memory and has a one-time programmable (OTP) feature that optimizes device sensitivity and quiescent output voltage (QVO) (field-free output) for a given application or circuit. During Allegro end-of-production testing, the A1369 can also be optimized for temperature optimization by programming sensitivity and QVO temperature coefficients.

These ratiometer Hall-effect sensors provide a voltage output proportional to the applied magnetic field. The user-adjustable quiescent voltage output value is approximately 50% of the supply voltage, and the output sensitivity is programmable from 8.5 mV/G to 12.5 mV/G (A1369EUA-10-T) and 22 mV/G to 26 mV/G (A1369EUA-24-T).

The linear device offers excellent performance for industrial applications requiring high sensitivity and guaranteed performance over a wide temperature range of –40°C to +85°C.
