Description
TS3809/3810 Series Taiwan Semiconductor Microprocessor Reset Circuit GENERAL .
The TS3809/3810 series are used for microprocessor (µP) supervisory circuits to monitor the power supplies in µP and digital systems.
Features
* High Accurate ±2%
* Precision monitoring of +3V, +3.3V, and +5V
Power supply voltage
* Fully specified over temperature
* Available in three output configurations
* Push-Pull RESET low output (TS3809)
* Push-Pull (RESET) high output (TS3810)
* 200ms typ. Power-on reset
Applications
* since most µP and other circuitry is inoperative with VCC below 1V. However, in applications where reset must be valid down to 0V, adding a pull down resistor to reset causes and stray leakage currents to flow to ground, holding reset low (Figure 2.) R1’s value is not critical; 100K is large enough n
