PST3121, PST, 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
