Switch Detect interface, 33 channel, Mono, 48 LQFP

The CD1030 is a multiple switch detection interface (MSDI) designed to detect the closing and opening of up to 33 switch contacts. The switch status, either open or closed, is transferred to the microprocessor through a SPI in automotive environments.\nThis SMARTMOS® device features a 35-to-1 analog • Fully functional operation 4.5V ≤ VBATP ≤ 36V\n• Full parametric operation 6.0V ≤ VBATP ≤ 28V\n• Operating switch input voltage range from -1.0V to 36V\n• 12 programmable inputs (switches to battery or ground)\n• 21 switch-to-ground inputs\n• Selectable wetting current (2.0, 6.0, 8.0, 10, 12, 14, ;
