MC34978AEKR2 Description

Short technical summary and product information.

The MC34978AEKR2 from NXP Semiconductors is a versatile 22-channel multiple switch detection interface IC. It is designed to monitor the open or closed status of up to 22 switch contacts, transferring this information to a microprocessor unit (MCU) via a serial peripheral interface (SPI).

 

This device offers selectable wetting currents ranging from 2 mA to 20 mA and supports both Pulse and Continuous wetting operations. It operates fully from 4.5 V to 36 V, with full parametric operation from 6.0 V to 28 V. The IC includes a 24-to-1 analog multiplexer for reading inputs as analog signals, and features integrated battery and temperature monitoring.

 

Available in a 32-SOIC-EP package, the MC34978AEKR2 is suitable for surface mount applications. Its low-power mode current consumption makes it ideal for automotive and industrial products requiring low sleep-state currents. The device also features an active interrupt output on change-of-switch state.
