UN8HX SOT23-5 ORIGINAL
Single 4.2V 500mA small size Lithium charge management IC
SOT23 package
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. When reached, the float
voltage and the charging current falls to a set current of 1/10, UN8HX automatically terminates the charging
process.
UN8HX features:
• Maximum programmable charge current of 800mA
• no external MOSFET, sense resistor, reverse diode
