A1343 Overview
The A1343 device is a high-precision, programmable Halleffect linear sensor integrated circuit (IC) with an open-drain output, configurable as pulse-width modulated (PWM) or single edge nibble transmission (SENT), for both automotive and nonautomotive applications. The signal path of the A1343 provides flexibility through external programming that allows the generation of an accurate and customized output voltage...
