Pins
Name
Type
Function
C5
DEN
Input
Reserved. This pin must be connected to a 10kΩ resistor to the VDD18 pin.
D1, D2, D3,
D4, D5, D6
OUT
Output
Regulated output voltage pin. Connect two 10μF capacitors from this pin to GND. The
default voltage is set to 12V when the VOSET pin is pulled up to the VDD18 pin through a
10kΩ resister. For more information about VOSET, see section 8.2.
E1, E2, E5, E6,
F2, F3, F4, F5
VRECT
Output
Output voltage of the synchronous rectifier bridge. Connect three 10μF capacitors and a
0.1µF capacitor in parallel to GND. The rectifier voltage dynamically changes as the load
changes. For more information, see the typical waveforms in section 6.
F1
VDD5V
Output
Internal 5V regulator output voltage for internal use. Connect a 1μF capacitor from this pin
to ground. Do not load the pin.
F6
VDD18
Output
Internal 1.8V regulator output voltage. Connect a 1μF capacitor from this pin to ground.
Do not load the pin.
G1
BST1
Output
Boost capacitor for driving the high-side switch of the internal rectifier. Connect a 15nF
capacitor from the AC1 pin to BST1.
G2, H1, H2,
AC1
Input
AC input power. Connect these pins to the resonant capacitance CS (C1, C2, C3, and C5
in Figure 24).
G3
RSV3
Input
Reserved pins. This pin must be connected to the OUT pin. Do not leave this pin floating.
G4
RSV1
–
Reserved for internal use. Do not connect.
G5, H5, H6
AC2
Input
AC input power. Connect to the Rx coil (L1 in Figure 24).
G6
BST2
Output
Boost capacitor for driving the high-side switch of the internal rectifier. Connect a 15nF
capacitor from the AC2 pin to BST2.
H3
RSV2
–
Reserved pins. This pin must be connected to the OUT pin. Do not leave this pin floating.
H4
TS/EOC
Input
End of Charge (EOC) and remote temperature (TS) sensing for over-temperature
shutdown. For remote temperature sensing, connect to the NTC thermistor network. If not
used, connect this pin to the VDD18 pin through the 10kΩ resistor. For EOC, connecting
this pin to ground will send the End Power Transfer (EPT) packet to the transmitter to
terminate the power. For more information, refer to section 8.9.
