Door keypad & reader

Door keypad and reader design resources and block diagram


Our integrated circuits and reference designs help you differentiate your door keypad and reader design for access authentication, while ensuring energy efficiency for longer battery life. Our latest technologies provide advanced features such as touch sense, wired/wireless connectivity and proximity sensing.

Door keypads and readers often require:

  • Low quiescent current power management for long battery life and battery monitoring
  • Support for multiple wireless standards (BLE, Wi-Fi, Sub-1GHz, 2.4GHz)
  • Low-power capacitive touch sensing to eliminate mechanical buttons
  • Robust ESD protection for keypads, buttons and wired interfaces
