Description
These ICs function in a variety of CPU systems and other logic systems to detect power supply voltage and reset the system accurately when power is turned on or interrupted.
This series has been represented in the past by PST574/PST575, but these new low reset type system reset ICs expand the delay time series with a counter timer using an analog/digital hybrid circuit.
Specifications and features
- Fixed delay time setting by counter timer
- Excellent delay time temperature characteristics ±800ppm/°C
- Low operating limit voltage 0.65V typ.
- Hysteresis voltage provided in detection voltage 50mV typ.
- Current consumption for no-load ICCL=300µA typ. ICCH=200µA typ.
- 5 delay time products available: PST591 50ms, PST594 400ms, PST592 100ms, PST595 800ms, PST593 200ms
- Each product has 9 detection voltage ranks: C : 4.5V typ. H : 3.1V typ. D : 4.2V typ. I : 2.9V typ. E : 3.9V typ. J : 2.7V typ. F : 3.6V typ. K : 2.5V typ. G : 3.3V typ.
