CMOS System Reset PST3XXX

Description of Operation

(1) VDD > VS, VOUT: H (M1: ON, M2, M3: OFF)

When VDD is gradually lowered from the above state, detection voltage is as follows.

Detection voltage: (R1 + R2 + R3) / (R2 + R3)

VREF

(2) VDD < VS, VOUT: L (M1: OFF, M2, M3: ON)

When VDD is gradually raised from the above state, release voltage is as follows.

Release voltage = (R1 + R2) / (R2)

VREF

(3) Hysteresis voltage = (release voltage) - (detection voltage).

(4) When VDD drops and goes below the minimum operating voltage, output is undefined; when output is

pulled up, output becomes VDD.

(5) VREF and detection resistors

1) The reference voltage source (VREF) for this IC is 0.8V typ. This gives excellent low power consumption

and temperature characteristics.

2) The high resistance process is used for resistors R1, R2 and R3 to achieve low consumption current for

the IC.

(6) Through current flows momentarily for detection and release. When using high VDD pin impedance, the

through current may cause oscillation.

(Example) Detection voltage changed by external settings

* The IC input voltage fluctuates due to the

through current

R11 voltage drop, and

an oscillation state where detection and

release are repeated may occur.

* With CMOS output types, do not use as

shown in the diagram at left.
