The MCZ33972AEWR2 from NXP Semiconductors is a Multiple Switch Detection Interface IC with Suppressed Wake-up functionality. It is engineered to detect the closing and opening of up to 22 switch contacts, transferring their status to a microprocessor unit (MCU) via a serial peripheral interface (SPI).
This device operates within a supply voltage range of 5.5 V to 26 V and supports switch input voltages from -14 V to 40 V. It offers selectable wetting currents of 2.0 mA or 16.0 mA and features 8 programmable inputs along with 14 switch-to-ground inputs. The MCZ33972AEWR2 includes a 22-to-1 analog multiplexer for analog input reading and provides an active interrupt on switch state changes.
Designed for automotive and industrial applications requiring low sleep-state currents, the MCZ33972AEWR2 has a typical standby current of 120 µA. It operates in Normal and Sleep modes, with Normal mode allowing device programming and switch monitoring, while Sleep mode conserves power. The IC is housed in a 32-SOIC package and operates over an extended temperature range of -40 °C to 125 °C.
