+Single cell LiFePO4 charging ([CN3058E](https://datasheet.lcsc.com/szlcsc/ShangHai-Consonance-Elec-CN3058E_C112011.pdf)) and protection ([HY2112](https://datasheet.lcsc.com/szlcsc/1810010241_HYCON-Tech-HY2112-BB_C161942.pdf)) board with load sharing power path management, 3.3V output und an additional switchable output. 
 
 The board was developed for 3.3V projects that are operated both by battery and external power. The load sharing system interrupts the connection between the battery and the load when an external power supply is connected. In this case, the project is powered by the external power supply and the 3.3V voltage regulator while the battery is being charged. This protects the battery and increases its lifespan. Without an external power supply, the project is powered directly by the battery, which means that the output voltage depends on the battery charge level (about 2.7 - 3.5V). Furthermore the board is equipped with an additional output port (SL) that can be switched via the built-in MOSFET. If the EN pin is pulled to ground, for example via a GPIO pin of a microcontroller, then the SL output is activated. The maximum output current is 1A.

+# Working Principle
+For battery charging the [TP4056](https://datasheet.lcsc.com/szlcsc/1904031009_TPOWER-TP4056_C382139.pdf) (U1) is used. The TP4056 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. The charge voltage is fixed at 4.2V and the charge current (max 1000mA) can be programmed externally with a single resistor (R3). The TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. Other features include current monitor, under voltage lockout and automatic recharge.
+
+For the battery protection (overcharge, overdischarge, overcurrent and short circuit protection) the [DW01A](https://datasheet.lcsc.com/szlcsc/1901091236_PUOLOP-DW01A_C351410.pdf) (U2) is used in combination with two [FS8205](https://datasheet.lcsc.com/szlcsc/Fortune-Semicon-FS8205_C32254.pdf) dual MOSFETs in parallel (Q1 + Q2). The DW01A is constantly measuring the voltage across the battery and the current flowing in (when charging) or coming out (when discharging). If something goes wrong it takes the battery out of the circuit by closing the MOSFETs which act like a switch between the negative side of the battery (B-) and ground. The overcurrent protection works by comparing the voltage drop across the MOSFET with the internal 150mV reference of the DW01A. As the RDS(on) of one FS8205 is around 2x25mOhm, the DW01A would close the MOSFET at 150mV/50mOhm = 3A if only one FS8205 were used. By using two FS8205 in parallel, the resistance is cut in half, so the DW01A shuts down at 150mV/25mOhm = 6A and one FS8205 must only handle half of the current (3A) which is well within its specs. In this way, up to 6 amps can flow from the battery into the boost converter with a maximum voltage drop of 150mV.
+
+To step up the voltage to 5V the [FP6277](https://datasheet.lcsc.com/szlcsc/Feeling-Tech-FP6277XR-G1_C88312.pdf) low-cost synchronous boost converter is used (U3). Instead of a diode that is used in conventional boost converters, it switches a second built-in MOSFET in sync with the first via the PWM signal. This significantly increases efficiency and thus higher output currents are possible.
