摘要: An electronic device (100) having n circuit portions (120a, 120b, ...,120n) each connected to a supply rail (102) through respective coupling elements (110a, 110b, ..., 110n) is arranged for gradual self-timed powerup/powerdown of the under control (240a, 240n-1) prevent occurrence power surges during powerup (100). When first portion (120a) has sufficiently been powered up and element (110a), (240a) switches second (110b) conductive state, thereby enabling (120b). In similar fashion, can be down in manner (112a, 112b, ...,112n), which respectively connect 120n) further (104).
