- Description The NXP® MC33972 multiple switch detection interface with suppressed wake-up is designed to detect the closing and opening of up to 22 switch contacts. The switch status, either open or closed, is transferred to the MCU through a SPI Features a 22-to-1 analog multiplexer for reading inputs as analog. The analog input signal is buffered and provided on the AMUX output pin for the MCU to read Two modes of operation:Normal: allows programming of the device and supplies switch contacts with pull-up or pull-down current monitoring switch change of state Sleep: provides low quiescent current, making MC33972 ideal for automotive and industrial products requiring low sleep state currents
