2.1 I/O Descriptions

Table 2-1 lists the input and output connections available on this EVM and the respective descriptions.

Table 2-1 EVM I/O Connections
I/O ConnectorDescription

J1 – AD external adapter input

J2-GND

Power can be provided to simulate an external adapter applied, max voltage 20V.

J3 – Output voltage

J4-GND

Output voltage is 5V in wireless power mode up to 1A.
J5 – TS and return connectorExternal connection for temperature sense resistor, see the BQ51013C data sheet for additional information.
JP1 – EN1 Enable 1Enable signal input that allows the system to enable or disable wireless charging or AD input.
JP2 – EN2 Enable 2
JP3 – TS Fixed or ADJEnables the TS adjustment feature using R3. The Fixed position sets voltage at the TS pin to a safe value.
JP4 – Pull-up to out or VzEN1 / 2 pull-up can be powered from OUT or RECT. Vz is derived from RECT through a resistor and Zener diode D2.
JP5 – DNPNot used, do not install.
JP6 – ILIM Fix or ADJMax output current is set by the ILIM pin. In the FIX position, the current is set to a fixed value. In the ADJ position the current is set by R16.
