Low-Cost 22-CH Multiple Switch Detect Interface

The CD1020 is a cost-optimized switch detection interface device (MSDI) 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). This SMARTMOS device ? Designed to operate 6 V ≤ VBATP ≤ 36 V\n? Switch input voltage range -14 V to VPWR, 36 V Max.\n? Interfaces directly to an MCU using 3.3 V / 5.0 V SPI protocol? Selectable wake-up on change of state\n? Selectable wetting current (2, 8, 12, or 16mA)\n? 8 programmable inputs (switches to battery or ;
