Toote ülevaade

The RT9458WSC from Richtek is a switch-mode single cell li-Ion battery charger with USB-OTG in 20 pin WLCSP package. It integrates a synchronous PWM controller, power MOSFETs, input current sensing, high accuracy voltage regulation and charge termination circuits. The RT9458 also features USB On-The-Go (OTG). The RT9458 optimizes the charging task by using a control algorithm to vary charge rate via different modes, including pre-charge mode, fast charge mode and constant voltage mode. The key charge parameters can be programmed via the I2C interface. The RT9458 resumes the charge cycle whenever the battery voltage falls below an internal threshold and automatically enters sleep mode when the input power supply is removed. It is used in cellular telephones, personal information appliances and MP3 players.
  • Support quick start for charger, high accuracy voltage/current regulation
  • Input current regulation of 100mA/500mA/700mA/1A & built-in input current sensing and limiting
  • Minimum input voltage regulation of 4.1V to 4.7V per 0.1V step
  • Integrated power MOSFETS for up to 1.55A charge rate & thermal regulation and protection
  • Integrated sensing resistors for charging current sensing & over-temperature protection
  • Input over-voltage protection, operating temperature range from -40°C to 85°C
  • VIN OVP threshold voltage of 7V, sleep-mode deglitch time of 128ms, automatic charging
  • VIN supply current of 10mA at PWM switching, ICHRG = IBAT = 0mA
  • Battery voltage regulation of 4.44V, output charging current of 1.55A
