... MB3807A BLOCK DIAGRAM EN1 EN0 Note: The MB3807A contains a pair of above circuit blocks. BLOCK DESCRIPTION The SWIN1 and SWIN2 pins are connected to the 12-V and 3.5/5.0-V power supplies, respectively. The SWOUT pin is connected to the V power supply pin of the flash memory. PP When conditions, EN1 = “H” and EN0 = “L” are established in an attempt to write data to flash memory, the switch- on circuit (charge pump) on the SW1 side is activated ...
