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.
Weight: 0.63 g (typ.)
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.
