(1) Super low consumption current (2) High precision detection voltage (3) Hysteresis characteristic (4) Operating range (5) Wide operating temperature range (6) Detectio.

(1) Microcomputer, CPU, MPU reset circuits (2) Logic circuit reset circuits (3) Battery voltage check circuits (4) Back-.

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 .
