Problems solved by technology

[0010] Therefore, from the above description, it can be found that the packaging structure disclosed by Pavier et al. is actually very complicated. If it is completed by semiconductor technology, its complexity may be reduced.
But it chooses to realize it with printed circuit boards. The layered circuit boards need to be etched, aligned, drilled, and resistively connected, which makes its entire process very complicated.
In this way, it is obvious that the plane area occupied by the packaging structure is reduced, but the overall process is complicated, which increases the cost
In addition, it is conceivable that the heat dissipation effect of the entire IC must be poor

Embodiment Construction

[0045] In summary, in the prior art, the separation of the battery management chip and the MOS transistor and the addition of external resistors and capacitors will make the entire package body have a considerable planar area: 21.9mm×3.55mm. However, the existing structure that is packaged into an integrated circuit has the problems of complicated process and high cost, which also makes its packaging not feasible. In addition, the resistance is enclosed inside. Heat dissipation is also a problem. The present invention therefore proposes a technique to overcome the above-mentioned problems. The detailed description is as follows:

[0046] In order to have a clearer understanding of the technical features, objectives and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

Abstract

The invention provides a packaging structure for a battery management integrated circuit. The packaging structure comprises a wire frame, a battery management chip, a charging and discharging controlled metal oxide semiconductor transistor, a resistor and a capacitor, wherein the wire frame is formed on a support; the wire frame is provided with a first contact pad, a second contact pad, and a pin and a connecting wire of the battery management chip; the battery management chip is connected with the first contact pad; the charging and discharging controlled metal oxide semiconductor transistor is connected with the second contact pad; the resistor and the capacitor are connected between the pin of the battery management chip and a pin of the battery management integrated circuit; and the wire frame of the packaging structure for the battery management integrated circuit is on one plane. The packaging structure for the battery management integrated circuit can be dramatically reduced.

Description

Technical field [0001] The present invention relates to a packaging structure of a battery management integrated circuit (IC), in particular to a packaging structure that can significantly reduce a battery management integrated circuit. Background technique [0002] Generally, the main source of electrical energy for portable computers, including mobile phones, tablet computers, and notebook computers, is a rechargeable lithium battery. The user may connect an AC to DC charger (adaptor) while using the laptop. After the external power supply is removed, the main power source for mobile phones and tablet computers will only be lithium batteries that can be recharged and discharged. [0003] The above-mentioned lithium battery is usually equipped with a battery management chip. The battery management IC includes battery electrical and non-electrical measurement circuits to manage the charging and discharging of the lithium battery to avoid overcharging or overdischarging to protect ...
