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.
