MC34671
feature limits the charge current when the IC internal temperature rises to a preset threshold. Temperature Device Package Range (TA) The MC34671 also protects the system with its input over-voltage protection (OVP) feature
. In addition, the MC34671 has a 2.6V falling MC34671AEP/R2 -40°C to 85°C 8-UDFN power-on-reset (POR) threshold, making it perfect to work with current limited power supplies. Three indication pins (PPR, CHG and FAST) can be simply interfaced to a microprocessor or LEDs. When no power supply is connected, or when disabled, the charger draws less than 1.0µA leakage current from the battery. Features
- No external MOSFET, reverse-blocking diode or current-sense resistor are required
- Guaranteed maximum 600m A programmable CC-mode current
- ±0.7% voltage accuracy over -20°C to 70°C
- ±5% current accuracy over -40°C to 85°C
- 28V maximum voltage for the power input with 11V over-voltage protection threshold
- 2.6V minimum input operating voltage
- Trickle charge for...
