DESCRIPTION
The A31102 is available in two package options: one includes a single monolithic integrated circuit (IC), and the second includes two electrically isolated ICs. Each IC consists of a high-precision programmable Hall-effect linear sensor with an open-drain output, which can be configured for either pulsewidth-modulated (PWM) or Single Edge Nibble Transmission (SENT) output protocols. Each IC within the A31102 package includes fully independent power and ground connections. The A31102 is an especially configurable and robust solution for the...
