Produktbeschreibung
The MC34671AEPR2 is a fully-integrated Battery Charger for Li-ion or li-polymer batteries. The high input voltage, up to 28V, eliminates the input over-voltage-protection circuit required applications. A typical charge cycle includes trickle, constant-current (CC) and constant-voltage (CV) charge modes. The CC-mode current is programmable up to 600mA 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 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 and cost. A charge current thermal fold back feature limits the charge current when the IC internal temperature rises to a preset threshold.
- No external MOSFET, reverse-blocking diode or current-sense resistor are required
- Guaranteed maximum 600mA programmable CC-mode current
- 2.6V Minimum input operating voltage
- Trickle charge for fully discharged batteries
- Charge current monitor
- Charge current thermal fold back
