3 Description
The bq500101 NexFET™ Power Stage is optimized
for wireless power applications covering the WPC
v1.2 medium power specification. The device can be
used for both the rail voltage control in fixed
frequency transmitter types as well as the coil drivers
for both fixed and variable frequency types. This
combination produces a high-current, high-efficiency,
and high-speed switching device in a small 3.5 × 4.5
mm outline package. In addition, the PCB footprint is
optimized to help reduce design time and simplify the
completion of the overall system design.

DESCRIPTION
NAME
1
VDD
Supply voltage to gate drivers and internal circuitry.
2
VDD
Supply voltage to gate drivers and internal circuitry.
3
PGND
Power ground, needs to be connected to Pin 9 and PCB
4
VSW
Voltage switching node – pin connection to the inductor.
5
VIN
Input voltage pin. Connect input capacitors close to this pin.
6
BOOT_R
7
BOOT
Bootstrap capacitor CBOOT connections. Connect a minimum 0.1 µF 16 V X5R, ceramic cap CBOOT from BOOT to
BOOT_R pins. The bootstrap capacitor provides the charge to turn on the Control FET. The bootstrap diode is
integrated. Boot_R is internally connected to VSW.
8
PWM
Pulse Width modulated tri-state input from external controller. Logic Low sets Control FET gate low and Sync FET
gate high. Logic High sets Control FET gate high and Sync FET gate Low. Open or High Z sets both MOSFET gates
low if greater than the tri-state shutdown hold-off time (t3HT)
