Abstract
The utility model discloses a USB intelligent charger with an LED display, which comprises an AC/DC conversion circuit, a charging management circuit and an MCU module. Both the charging management circuit and the MCU module are connected to the AC/DC conversion circuit. A sampling circuit is arranged between the two output ends of the charging management circuit. The sampling circuit is connected to the MCU module through an AD chip. The MCU module is further connected with a display module. The MCU control end is connected to the charging management circuit. When the USB intelligent charger is in use, the MCU module will monitor the remained power of external equipment in a real-time manner through the AD module and the sampling module and meanwhile make the remained power reflected on the display module in a real-time way. When the external equipment is detected by the MCU module to be fully charged, the MCU control end then controls the charging management circuit to stop charging. The energy is thus significantly saved. The USB intelligent charger thus complies with the green and environment-friendly lifestyle advocated nowadays.
