Embodiment Construction

[0028] In order to further reduce the number of pins, the MIC bias circuit pins can also be multiplexed as answer / hang up signal pins, which are respectively connected to the MIC bias circuit and GPIO bus in the terminal equipment for outputting the MIC bias circuit. Set the bias voltage generated by the circuit, and input the answer / hang up signal to the GPIO bus.

[0029] In order to further reduce the number of pins, the left earphone channel pin or the right earphone channel pin can be multiplexed as the FM antenna pin. Then the earphone left channel pin or the earphone right channel pin is not only connected to the codec module in the terminal, so as to output the left channel signal of the earphone or the right channel signal of the earphone, but also connected to the FM module in the terminal for Receive the FM signal and input it to the FM module.

[0030] The connector provided in the present invention can also support Capless technology, that is, the earphone refere...

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 thei...
