Abstract

The invention discloses a charge control method for a starting power source. The charge control method is implemented by the aid of a booster protection chip U9, a charge output circuit and 3 control ends CTL-CHG, CTL-INA and CTL-INB. The booster protection chip U9 is an FP5139 chip; an end GATE of the booster protection chip U9 in the charge output circuit is connected with a pole B of an NPN-type triode Q19 and a pole B of a PNP-type triode Q20 by a resistor R15; a pole E of the triode Q19 is in short circuit with a pole C of the triode Q20; a pole C of the triode Q19 is connected with a power source VCC-BAT by a resistor R16; a pole E of the triode Q19 is connected with a pole G of an NMOS (n-channel metal oxide semiconductor) transistor Q10 by a resistor R43, and a pole D of the NMOS transistor Q10 is connected with a joint of an inductor L4 and a diode D6; a pole S of the NMOS transistor Q10 and a pole E of the triode Q20 are grounded. The charge control method for the starting power source has the advantages that the external control ends are combined with the booster protection chip, accordingly, charge can be controlled, and the charge control method is high in safety and reliability.

Description

technical field [0001] The invention particularly relates to a charging control method for starting a power supply. Background technique [0002] The car starting power supply is a special-purpose mobile power supply. When using an external circuit to charge the energy storage module of the car starting power supply, if the current is too large, it will not only cause damage to the battery and circuit board, but also easily cause the explosion of the battery. Therefore, it is necessary to To carry out the necessary control on the charging process, it is necessary to design a charging control method for starting the power supply. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a charging control method for starting a power supply. The charging control method for starting a power supply adopts the combination of an external control terminal and a boost protection chip to realize charging control, and has high safet...
