MC33978 Datasheet - NXP

MC33978 22-channel multiple switch detection interface

The 33978 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 microprocessor unit (MCU) through a serial peripheral interface (SPI). Individually selectable input currents are available in Normal and Low-power (LP.

MC33978 Features

* Fully functional operation from 4.5 V to 36 V

* Full parametric operation from 6.0 V to 28 V

* Low-power mode current IBATP = 30 μA and IDDQ = 10 μA

* 22 Switch detection channels

* 14 Switch-to-Ground (SG) inputs

* 8 Programmable switch (SP) inputs
