It monitors USB D+/D- data line's signal, and automatically adjusts output voltage of power source output to optimize charge time. Under Voltage Lockout (UVLO) The LP103S had an UVLO internal circuit that enable the device once the voltage on the VPS voltage exceeds the UVLO threshold voltage. Power Source By pass a 2.2kΩ resistor through VBus to PS pin is recommended. It can limits the current flowing into the PS pin and thus into the shunt regulator at the PS pin to less than 8mA to protect chip. there are also recommended a decoupling capacitor through PS pin to GND. Fault Monitor It is needed to detect a loaded condition and trigger protection in case of loading in the absence of a portable device. D+/D- Data Lines All protocol transients by USB data line . Temperature Monitor If additional system level thermal protection is required. Feed Back Output Set the output voltage by selecting the resistive voltage divider ratio. The voltage divider drops the output voltage to the system feedback voltage. Fixed 100kΩ with high-site divider resistor. Determine the low-side resistor R1 by the equation: VBUS = (100k ÷ RLS +1)×VFB Class A/B Selection The LP103S has a output voltage levels selection pin, which allows users to set operational class A or B. Connecting SEL pin to High-Level, users may operate the device at class B. When working with a class A, connect SEL pin to ground or leave it floating as SEL pin with internal pull down resistance. QC Enable For high current and low voltage application, there are good solution to solve it by pull-low QC_EN Pin. It will disable Qualcomm® Quick ChargeTM 2.0/3.0 function. When working with QC 2.0/3.0, connect QC_EN to high or leave it floating as QC_EN pin is equipped with internal 2uA pull high currant. LP103S Version 0.1 MAR.-2019 Quickly Charger 2.0/3.0 Interface At power-up LP103S turns on switch S1 to check short-circuiting USB data lines D+ and D- for the initial handshake between DCP and PD as described in the USB BC1.2 specification. After the USB BC 1.2 handshake is completed, LP103S will turn off switch N1 if it detects a Quick Charge 2.0 or Quick Charge 3.0 compliant PD. Upon completion of the Quick Charge 2.0 and Quick Charge 3.0 handshakes, LP103S will turn on switch S2 and S3 connecting a resistor pull-down resistor to D-.

Here are some suggestions to the layout of LP103S design. 1. Connected all ground together with one uninterrupted ground plane, which include power ground and analog ground. 2. The input capacitor should be located as closed as possible to the VPS and ground plane. 3. The FBO pin of LP103S is connected to the FB pin of regulator and close placement of two ICs is recommended. FBO 3 2 1 D+ RD LP103S 4 GND 5 Cin 6 Rin DVBUS Figure 4.
