IP5521
The IP5521 is a multi-functional power management SOC that integrates a boost converter, lithium battery charge 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 IP5521 allow it to use only a minimal number of external components during application, effectively reducing the overall solution size and lowering BOM costs. The IP5521 integrates a synchronous boost DC-DC converter with an internal power transistor, providing a maximum output current of 300mA and a boost efficiency of up to 92%. The DC-DC converter switching frequency is 1.0MHz, supporting low-cost inductors and capacitors. The IP5521's linear charging provides a maximum charging current of 500mA, with flexible configuration of the maximum charging current. It has built-in chip temperature protection and intelligent input voltage regulation of the charging current. The IP5521 can achieve independent in-case detection of dual TWS earphones. Upon detecting earphones in the case, it automatically enters the earphone charging mode, and automatically enters sleep mode after the earphones are fully charged, with a minimum static current of 25uA. The IP5521 supports 1/2/3/4 LED battery level indicators.
