IP5518V
The IP5518V is a multi-functional power management SoC that integrates a 5V boost converter, lithium battery charging management, and battery power indication. It provides a complete power solution for TWS Bluetooth earphone charging cases. The high integration and rich features of the IP5518V allow it to use very few external components during application, effectively reducing the size of the overall solution and lowering the BOM cost. The IP5518V integrates a 5V output, synchronous rectification boost DC-DC converter with built-in power transistors, providing a maximum output current of 300mA and a boost efficiency as high as 93%. The DC-DC converter switching frequency is 1.5MHz, supporting low-cost inductors and capacitors. The IP5518V's linear charging provides a maximum charging current of 500mA and allows flexible configuration of the maximum charging current. It has built-in IC temperature and input voltage intelligent charging current adjustment functions. The IP5518V can achieve independent in-case detection for TWS earbuds. Upon detecting earbuds in the case, it automatically enters the earbud charging mode. After the earbuds are fully charged, it automatically enters the sleep state, with the quiescent current dropping to a minimum of 20uA. The full-charge current can be flexibly customized, with a high charging current detection accuracy of up to 1mA. The IP5518V has a built-in MCU that allows flexible customization of 4/3/2/1 LEDs or a 188 digital tube power display. It has a built-in 12-bit ADC for accurate battery power calculation. The IP5518V uses a QFN24 package.
