7.4.1 INTB Pin Modes

The INTB pin is a configurable output pin which can be used to drive an interrupt on an MCU. The LDC1001-Q1 device provides three different modes on the INTB pin which include:

  1. Comparator mode
  2. Wake-up mode
  3. DRDY mode

The LDC1001-Q1 device has a built-in high trigger and low trigger threshold registers that can be a comparator with programmable hysteresis or a special mode that is used to wake up an MCU. The following sections describe these modes in detail.
