The MCZ33972AEK from NXP Semiconductors is a Multiple Switch Detection Interface IC with suppressed wake-up functionality. It is designed to detect the closing and opening of up to 22 switch contacts, transferring the status to a microprocessor unit (MCU) through a serial peripheral interface (SPI).
This device features a wide operating voltage range of 8V to 26V and supports switch input voltages from -14V to 40V. It offers selectable wetting current options of 2.0 mA or 16.0 mA. The IC includes 8 programmable inputs and 14 switch-to-ground inputs, along with typical standby currents of 100 µA for VPWR and 20 µA for VDD.
The MCZ33972AEK operates in Normal and Sleep modes. Normal mode allows device programming and monitors switch changes, while Sleep mode provides low quiescent current, making it suitable for automotive and industrial products. The device is housed in a 32-SOIC-EP package and is surface-mount compatible.
Key electrical characteristics include an 8V to 26V operating voltage and SPI serial interface. The operating temperature range is -40°C to 125°C. The IC is RoHS3 compliant.
