TWS Charging Case IC

Multi-function power management SoC with MCU, boost converter, lithium battery charge management, and battery level indication——IP5528

realme Buds Air 5 Pro IP5528 inside

 

  • > Only one inductor is needed to achieve the voltage rise and fall function, supporting low-cost inductors and capacitors
  • > The synchronous boost system provides a rated 400mA output current with a conversion efficiency of up to 93%. Under light load, it automatically enters the sleep state and  the static current is reduced to 15µA.
  • > Switch charging technology, providing rated 1A charging current, charging efficiency up to 90%. Built-in chip temperature protection and input voltage intelligent regulation of charging current.
  • > Built-in 12-bit ADC for precise measurement of battery voltage and current. Support 1/2/3/4 LED power display and digital power display.
 
A versatile power management SoC with integrated boost converter, lithium battery charge management, and battery level indication——IP5518H
 
  • > Built-in synchronous rectifier boost DC-DC, power tube, provides a maximum output current of 400mA, boost efficiency up to 93%. The DC-DC converter has a switching frequency of 1.0MHz and can support low-cost inductors and capacitors.
  • > Linear charging provides a maximum charge current of 500mA, and the maximum charge current can be flexibly configured. Built-in chip temperature protection and input voltage intelligent regulation of charging current.
  • > It can realize the independent storage detection of TWS two earphones, automatically enter the earphone charging mode after detecting the earphones in the storage, and automatically enter the sleep state after the earphones are full, and the minimum static current can be reduced to 20uA. The headphone can be flexibly customized with full current detection accuracy up to 1mA.
  • > Built-in 8bits MCU, can be flexibly customized 4/3/2/1 LED or 188 digital tube power display. The built-in 12bits ADC accurately calculates the battery level.
