... Input channels. This address is latched at the falling edge of the SCLK, which starts an A/D conversion. A1 Input Input Input Input 4. Digital Input. This is the microPort™ serial clock input. The TC3404 comes out of Sleep mode and a conversion cycle begins when this pin is driven low. After the conversion starts, each additional falling edge (up to six) detected on SCLK for t the A/D resolution by one bit ...

... SCLK transitions during t ignored. After each high to low transition of SCLK, in the t val, the SDAT output is driven high by the TC3404 to acknowledge that the resolution has been decre- mented. When the SCLK returns high or the t ends, the SDAT line returns low (see Figure 3-2). When the conversion is complete SDAT is driven high ...

... The Power Fail detector is a comparator in which the inverting input is connected to the internal voltage reference. The non-inverting input is the PFI pin of the TC3404 and the PFO pin is the active low, open drain output. This comparator is suitable as an early warning fail or low battery indicator typical application, ...
