5. Examples of Applications

To allow these Supply Voltage Supervisors to be used in a variety of systems, they have been provided with various



TLC7701: This device is needed when there are no “standard” supply voltages to be monitored. The desired

threshold voltage can be set by means of external voltage divider (See Section 3).



TLC7703: For battery operated applications with nominal supply voltages of 3.3V, but with which a minimum

supply voltage of 2.7V is permissible, in order to extend the operating time.



TLC7733: For applications requiring a nominal supply voltage of 3.3V (±10%).



TLC7705: For applications in microcomputer systems, which operate from a supply voltage of 5V.

5.1 Voltage Monitoring

For the construction of a circuit to monitor a “standard” voltage, the only additional external component needed is the
