CD1030 Multiple Switch Detection Interface IC

NXP CD1030 Multiple Switch Detection Interface IC detects the closing and opening of up to 33 switch contacts. CD1030 transfers the switch status of open or closed to the microprocessor unit (MCU) through a serial peripheral interface (SPI). This NXP SMARTMOS interface IC also features a 35-to-1 analogue multiplexer for reading the input channels as analogue inputs. CD1030 includes independent programmable wetting currents (2 to 20mA) and also features a battery and temperature monitor. CD1030, which has normal and low-power modes, is ideal for automotive and industrial applications that require low sleep-state currents.
