1 / 19 page TD62650,651,652FG 2006-06-14 1 TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD62650FG,TD62651FG,TD62652FG 5V POWER SUPPLY & SUPPLY MONITORING + COMMUNICATIONS IC The TD62650FG 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% (TD62650FG / 652FG) or 85% (TD62651FG) 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. The suffix (G) appended to the part number represents a Lead (Pb)-Free product. FEATURES Accurate output : 5V ± 0.25 V Output PNP Tr incorporated : Current capacity ; 300 mA (max) Power−on Reset timer incorporated Watchdog timer incorporated Small flat package sealing : SSOP30 pin (1 mm pitch) Difference 1 CHARACTERISTIC TD62650 / 652FG TD62651FG Reset Detecting Voltage 5V / 92% 5V / 85% Difference 2 Time setting resistance 22 kΩ for power−on reset / watchdog timer, and PULL resistance of 4.7 kΩ for RESET pin.
