Connector and Test Point Descriptions

4.1.1

J1 – AD External Adapter Input, J2-GND

Power can be provided to simulate an external adapter applied to the receiver. When this is done, an End
Power Transfer signal is sent to the transmitter which enters a low power state. External adapter voltage
must be a minimum of 4 V but not exceed 20V.

4.1.2

J3 – Output Voltage, J4-GND

Output voltage is 5 V in wireless power mode up to 1 A or adapter voltage if adapter is used.

4.1.3

J5 – TS and Return Connector

External connection for Temperature Sense Resistor, see data sheet for additional info.

4.1.4

J6 – Programming Connector

This connector is only useful at factory level.

4.2

Jumpers/Switches

The control jumpers are described in the following paragraphs.

4.2.1

JP1 – EN1 Enable 1

One of two Enable signals that controls the Adapter and Wireless power transfer. Low on EN1 enables the
wireless power transfer; High disables the wireless power transfer. The Default Shorting jumper setting is
Low.

4.2.2

JP2 – EN2 Enable 2

One of two Enable signals that controls the Adapter and Wireless power transfer. Low on EN2 enables the
adapter power transfer also High disables Comm-I

ILIM

. Default Shorting jumper setting is Low.

4.2.3

JP3 – TS Enable or Disable

This jumper enables the TS adjustment feature using R3. The Disable position sets voltage at the TS pin
to a safe value. The Default Shorting jumper setting is disabled

4.2.4

JP4 – Pull-Up to Out or Vz

EN1 and EN2 pull-up along with LED D1 can be powered from OUT or RECT. Vz is derived from RECT
through a resistor and zener diode.

4.2.5

JP5 – CS100 TS Enable or Disable

Only used for bq51014 device. This jumper along with R14 and R13 will enable the Charge Status 100%
feature. See data sheet for additional info. Open will disable.

4.2.6

JP6 – ILIM Fix or ADJ

Max output current is set by I-lim pin. In the FIX position current is set to 1.2A max. In the ADJ position
current is set by R16.

4.3

Test Point Descriptions

The test points are described in the following paragraphs.

4.3.1

TP1 – AD_EN

This push-pull driver for the external PFET connects the Adapter and the Output from the bq51013.
