Features

AI Translation
  • Highly integrated solution for switching power supplies requiring dual control loops for constant voltage and constant current
  • Integrated ±1% accuracy 1.21V voltage reference (±0.5% for ME4312C), a 74mV low voltage reference (212mV for ME4312C), an externally adjustable ultra-low voltage reference, and three op-amps
  • 1.21V voltage reference combined with one op-amp enables ME4312 to generate an ideal voltage for power adapters and battery chargers
  • Low voltage reference combined with another op-amp enables ME4312 to generate an ideal current limit for output current limiting and constant current sensing
  • ME4312A integrates a 9mV voltage reference combined with one op-amp to generate an ideal LED switching circuit, with current sensing and LED switching circuit adjustable via the Ictrl pin
  • Red LED on and green LED off during normal charging; green LED on and red LED off when charging current drops to 12% of the current limit
  • 11% hysteresis implemented in the LED switching comparator to prevent red/green LED toggling after full charge detection
  • ME4312B/C supports lower voltage reference adjustment and LED switching point modification via external resistor on the Ictrl pin, fully customizable per customer requirements
  • Constant voltage and constant current control
  • Precise internal voltage reference
  • Minimal external components
  • Easy compensation
  • Adjustable LED switching circuit
  • Wide operating voltage range: 3~40V
  • Low operating current
  • Charge status indication
  • Few peripheral components, low overall system cost
