Application Information
The LD8200A is a current advertisement and blocking MOSFET controller for USB Type-C adapter or Charger. The Function are includes Type -C cable detector, external over thermal protection and over voltage protection. The device operation in wide range input voltage 3.5V~20V, low quiescent current under 100uA. And the SOT-26 package to minimize the PCB size well as component counts and cost Current advertisement When the VCC pin voltage rises over UVLO(ON). The IC has output current of configuration channel to advertisement the USB type-C Adaptor or charger current level to UFP (Upstream Facing Port). Blocking P-MOSFET Controller When a type -C cable attaches have been completed. The P_CTL would pull low after 120mS than the blocking P -MOSFET will turn on. When the cable unattached, the P_CTL would pull high straightway the blocking P-MOSFET will turn off shortly. External Thermal protection The OTP circuit is implemented to sense whether there is any hot -spot of power circuit like power MOSFET or output rectifier. Once an over -temperature condition is detected, the OTP is enabled to shut down the controller to protect the controller. Typically, a NTC is recommended to connect with OTP pin. The NTC resistance will decrease as the device or ambient in high temperature. The relationship is as below. 𝑉𝑂𝑇𝑃 = 100𝑢𝐴 × 𝑅𝑁𝑇𝐶 When the V OTP is below the defined voltage threshold (typ. 0.1V), LD8200A will disable the P_CTL output and blocking off the VBUS. There are 2 conditions required to restart it successfully. First, cool down the circuit so that NTC resistance will increase and raise V OTP up above 1. 1V. Then, remove the VCC power to UVLO(OFF). Over Voltage Protection If VCC pin voltage is larger than 6.5V, the LD8200A would be turn off blocking P-MOSFET until the VCC Pin voltage decline to 5.6V then the LD8200A would turn on blocking P-MOSFET again. Internal Thermal protection When the junction temp erature reaches 140C approximately, the thermal sensor signals would turn off External Blocking P-MOSFET. The VBUS output voltage and current is cut off to UFP under the IC ’s junction temperature cools by 20.
