TLP1037A is a high-withstanding-voltage photo-interrupter for digital output. The device combines a high-optical-output GaAs infrared LED with a high-sensitivity, high-gain Si photo-IC. The photo-IC, which supports a wide range of systems (3.3 V to 12 V), enables the device to consume less power than conventional devices. The device also features a narrow slit width and high resolution.
The TLP1037A is a high‑withstanding‑voltage photointerrupter with a GaAs infrared LED and a high‑gain Si photo‑IC, intended for use in domestic appliances, office equipment, vending machines, ATMs and other electronic systems. It offers digital open‑collector output and can operate from 2.7 V to 15 V supply.
