TLC770X Datasheet, PDF (26/27 Pages) Texas Instruments – BiCMOS SUPPLY VOLTAGE SUPERVISORS

6. Summary
6.1 Design Check List
When considering the main features of the Supply Voltage Supervisor TLC770X, the various factors which need to
be taken into account when using this series of components can be summarized as follows.
1. Setting of the delay time t_d
Line operated power supply
Battery power supply
Oscillator (Start-up Time)
Reset program
Range of delay times t_d to be set
Switch-On Time
10 ms - 100 ms
0.03 ms - 30 ms
10 ms - 100 ms
Several microseconds
(20 ms)......500 ms
2. Circuit board construction
• Use of a blocking capacitor of 0.1 µF between the supply line and the Ground connection, in order to
avoid disturbances on the supply line.
• Connections to external components should be kept as short as possible.
• A star-shaped connection from the integrated circuit to Ground should be made (see Figure 23.).
• The Supply Voltage Supervisor should be situated in an interference-free environment on the edge of the
circuit board.
