CN3170
Overview: CN3170 is a single-cell lithium battery charge management chip that can be powered by solar energy. The device includes power transistors internally and does not require external current detection resistors and current limiting diodes. The internal adaptive charging current module can automatically adjust the charging current according to the current output capability of the input power supply. Users do not need to consider the worst-case scenario, and can maximize the use of the current output capability of the input power supply. It is very suitable for lithium battery charging applications powered by power supplies with limited current output capabilities, such as solar panels. CN3170 requires very few external components and is very suitable for portable applications. The thermal modulation circuit can control the chip temperature within a safe range when the device's power consumption is relatively large or the ambient temperature is relatively high. The internal fixed constant voltage charging voltage is 4.2V, which can also be adjusted upward through an external resistor. The charging current is set by an external resistor. When the input voltage is powered off, CN3170 automatically enters a low-power sleep mode, at which time the battery current is less than 3 microamps. Other functions include input undervoltage latch, automatic recharging, JEITA standard battery temperature monitoring, overcurrent protection during charging, and charging status/charging completion status indication. CN3170 is available in a heat-enhanced 8-pin SOP package (eSOP8).
