TD62650F

TD62650,651,652F TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD62650F,TD62651F,TD62652F 5V POWER SUPPLY & SUPPLY MONITORING + COMMUNICATIONS IC The TD62650F series covers products developed for use in microcomputer systems applicable to automatic vending machines. They produce an output voltage of 5 V ± 0.5 V without need for adjustment, through their accurate reference voltage and amplifier circuit. The 5V section can reset the system by outputting reset signals at power−on, and also output a reset signal when the 5 V output voltage drops below the specified 92% (TD62650F / 652F) or 85% (TD62651F) because of external disturbances or other problem. It also incorporates a watchdog timer for self−diagnosing the system. When the system malfunctions, the IC generates reset pulses intermittently to prevent the system from running away. The interface section incorporates three serial ports corresponding to the typical 24−V 4800 bps system in microcomputers. Weight: 0.63 g (Typ.)
