Embodiment Construction

[0024] The embodiments of the present invention reduce the number of pins of the connector by multiplexing the charging pins of the charger and the pins of the USB power supply in the connector.

[0025] In the terminal equipment, besides the connector, the above-mentioned multiplexing of pins also includes a power management module (PMU). Wherein, the connector includes a charging pin and two detection pins; these pins are connected to the PMU module; when the PMU module detects that the charging pin has a voltage input and the two detection pins are short-circuited, Enable the charger charging mode to receive current from the charging pin for charging; when it is detected that the charging pin has a voltage input, and the two detection pins are not short-circuited, enable the universal serial bus USB charging mode from the charging pin The charging pin receives current for charging. Here, the number of charging pins may be three.

[0026] The above connector may further in...

Abstract

A terminal device consists of power supply management module PMU and connector with a charge pin and two detection pins. It is featured as starting up charge mode of charger to receive current from charge pin for carrying out charge when voltage input on said charge pin is detected by PMU module and two said detection pins are short-circuit, starting up charge mode of universal serial bus USB to receive current from said charge pin for carrying out charge when voltage input on said charge pin is detected and two said detection pins are not short-circuited.

Description

technical field [0001] The present invention relates to the field of hardware interface technology, in particular to a terminal device, a connector, a charger and a charging method. Background technique [0002] With the enhanced functions of terminal equipment such as mobile phones, the requirements for interface functions of terminal equipment are also getting higher and higher. The terminal device is usually connected to the external device through a connector, so as to realize data transmission between the terminal device and the external device, charge the terminal device, and the like. [0003] Due to the enhanced function of the connector, more and more pins of the connector are caused. Table 1 below shows the pins included in a 24-pin connector and their functions. Among them, the functions of pins 9, 10, and 11 are used for charging, and the function of pin 21 is also used for charging. For such pins with the same function, different pins are used to realize their...
