PST3221 CMOS System Reset

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 vol.
