Abstract:

An electronic power control circuit includes a power conditioner circuit (120, 130) having a charging input line (116), a battery-related line (133) of the power conditioner circuit (120, 130), and a power voltage output line (137); and an anti-crash loop mechanism (170) coupled to the battery-related line (133) and to the power voltage output line (137) of the power conditioner circuit (120, 130), the anti-crash loop mechanism (170) having a control output line (172, PWGOOD) to be selectively active and inactive in response to voltage levels over time on the battery-related line (133) and on the power voltage output line (137) of the power conditioner circuit (120, 130).
