IC for System Reset PST591~595
IC for System Reset
Monolithic IC PST591~595 Series
Outline
This IC functions in a variety of CPU systems and other logic systems, to detect supply voltage and reset the
system accurately when the power is turned on or interrupted. It incorporates a fixed-delay time generation
circuit. These are other system reset ICs such as PST574 and PST575 (both conventional). In particular, this
IC is a low-reset type system reset IC having a counter timer comprising of analog/digital mixed circuits.
PST591- 595 have a different delay time respectively.
Features
1. Fixed delay time setting by counter timer
Excellent delay time temperature characteristics
±800ppm/°C
2. Low operating limit voltage
0.65V typ.
3. Hysteresis voltage provided for detection voltage
50mV typ.
4. No-load current consumption
ICCL=300A typ. ICCH=200A typ.
5. 5 models are available for different delay times.
PST591
50ms
PST594 400ms
PST592 100ms
PST595 800ms
PST593 200ms
6. Each model 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.
Packages
MMP-4A (PST59
M)
TO-92A (PST59
)
*The box represents a rank of detection voltage.
(MMP-4A has a manual reset pin, which should be connected to GND or NC during normal operation.)
Applications
1. Reset circuits for microcomputers, CPUs and MPUs
2. Reset circuits for logic circuits
3. Battery voltage check circuits
4. Back-up power supply switching circuits
5. Level detection circuits
6. Mechanical reset circuits
