MULTIPLE SWITCH DETECTION INTERFACE

Multiple Switch Detection Interface with Suppressed Wake-upThe 33972 Multiple Switch Detection Interface with suppressed wake-up 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) throug • Designed to operate 5.5 V ≤ VPWR ≤ 26 V\n• Switch input voltage range -14 V to VPWR, 40 V Max\n• Interfaces directly to MPU using 3.3 V/5.0 V SPI protocol\n• Selectable wake-up on change of state\n• Selectable wetting current (16 or 2.0 mA)\n• 8 programmable inputs (switches to battery or ground)\;
