Allegro MicroSystems Inc. Differential Cam Sensor IC A16100PUCCTN

The A16100PUCCTN is a three-wire differential Hall-effect sensor IC for camshaft applications, housed in a 3-pin SIP package with a matte-tin-plated leadframe. It features programmable switch points via EEPROM, true zero-speed operation, and air gap independent switching. The device operates with a supply voltage of 4 to 24 V, supports ambient temperatures from -40°C to 160°C, and has an open-drain output capable of sinking up to 80 mA. Differential sensing provides immunity to stray magnetic fields, and it includes integrated EMC components for automotive compliance. The output rise time is up to 10 µs and fall time is up to 2.5 µs with a 1 kΩ pull-up. Magnetic sensitivity ranges from 60 to 1200 G with a differential offset tolerance of ±200 G.
