DESCRIPTION
Programming pin for the over current limit. Connect external resistor to VSS. Size R ILIM with
the following equation: R ILIM = 250 / I MAX where IMAX is the expected maximum output current

I/O
of the wireless power supply. The hardware current limit (IILIM) will be 20% greater than IMAX
or 1.2 x 1 MAX . If the supply is meant to operate in current limit use
R ILIM = 300 / I ILIM
R ILIM = R1 + 140
Connect this pin to the wired adapter input. When a voltage is applied to this pin wireless
charging is disabled and AD_EN is driven low. Connect to GND through a 1 μF capacitor. If

unused, capacitor is not required and should be grounded directly. For the bq51014, there is
an OVP protection of 12.5 V. If the AD voltage is greater than 12.5 V, wireless charging will
remain active.
Push-pull driver for external PFET connecting AD and OUT. This node is pulled to the higher

of OUT and AD when turning off the external FET. This voltage tracks approximately 4 V below
AD when voltage is present at AD and provides a regulated VSG bias for the external FET.
Float this pin if unused.
Must be connected to ground via a resistor. If an NTC function is not desired connect to GND
with a 10 k ? resistor. As a CTRL pin pull to ground to send end power transfer (EPT) fault to

the transmitter or pull-up to an internal rail (i.e. 1.8 V) to send EPT termination to the
transmitter. Note that a 3-state driver should be used to interface this pin (see the 3-state
Driver section for further description)

200 Ω /%. Set the termination threshold by applying the following equation R TERM = %I MAX x
K TERM where %IMAX is the desired percentage of the maximum output current when
termination should occur (i.e. 10% of 1 A = 0.1 mA)
