The MC33972TEWR2 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 their status to a microprocessor unit (MCU) via a serial peripheral interface (SPI).
This device supports a wide operating voltage range for VPWR from 5.5 V to 26 V, with switch input voltage tolerance from -14 V to 40 V. It offers selectable wetting currents of 2.0 mA or 16.0 mA and includes 8 programmable inputs and 14 switch-to-ground inputs. The typical standby current is low, making it suitable for power-sensitive applications.
The MC33972TEWR2 is available in a 32-SOIC Wide package and is designed for surface mount applications. It operates across a temperature range of -40 °C to 125 °C.
Key features include selectable wake-up on change of state and an active interrupt output on switch state changes. The device also includes a 22-to-1 analog multiplexer for reading inputs as analog signals.
