    UN8HX Single 4.2V 500mA small size Lithium charge management IC Also supplied as 2YL6, H1JC, 54B4, G5242 Constant current / constant voltage linear charger chip, primarily for single-cell Li-ion battery charging applications. Using the SOT23 small package and minimal number of external components, ideal for portable equipment applications. No external sense resistor, and at the same time due to the internal MOSFET structure, so no external reverse diode. The thermal feedback circuits so UN8HX can adjust the charge current to limit the chip temperature in highpower and high ambient temperatures. Charging voltage is fixed at 4.2V, charging current can be set by an external resistor.
