NXP MC34673AEPR2 Battery Charger for 1 Cell of Li-Ion Li-Pol 6.6V Input 4.23V / 1.2A Charge UDFN-8

The MC34673AEPR2 is a 1.2A high input voltage Fully-integrated Charger for Li-ion or Li-Polymer batteries. The high input voltage, up to 28V, eliminates the input overvoltage protection circuit required in handheld devices such as PDAs, cell phones, portable video game players and digital still cameras. A typical charge cycle includes trickle, constant-current (CC) and constant-voltage (CV) charge modes. The CC-mode current is programmable up to 1.2A with an external resistor. The voltage across the external resistor is also used to monitor the actual charge current. The constant voltage is fixed at 4.2V with 0.7% accuracy over a -20°C to 70°C temperature range. The trickle-mode current is preset to 20% of the CC-mode current when the battery voltage is lower than the trickle-mode threshold. The end-of-charge (EOC) current threshold is preset to 10% of the CC-mode current to save the board space.

• No external MOSFET, reverse-blocking diode or current-sense resistor are required
• Trickle charge for fully discharged batteries
• Charge current monitor
• Charge current thermal foldback
