Pin Functions

PIN TYPE DESCRIPTION
NAME NUMBER
AC1 B1, B2, B3 I AC input power from receiver resonant tank
AC2 B4, B5, B6 I
AD E2 I Adapter sense pin
AD-EN E3 O Push-pull driver for dual PFET circuit that can pass AD input to the OUT pin; used for adapter mux control
BOOT1 C1 O Bootstrap capacitors for driving the high-side FETs of the synchronous rectifier
BOOT2 C6 O
CLAMP1 E1 O Open-drain FETs used to clamp the secondary voltage by providing low impedance across secondary
CLAMP2 E6 O
COMM1 F1 O Open-drain FETs used to communicate with primary by varying reflected impedance
COMM2 F6 O
CM_ILIM G3 I Enables or disables communication current limit; can be pulled high to disable or pull low enable communication current limit
EN1 E4 I EN1 and EN2 are used for I2C communication in bq5020. Ground if not needed. SCL and SDA are used in bq51021.
EN2 F4 I
FOD F2 I Input that is used for scaling the received power message
ILIM G2 I/O Output current or overcurrent level programming pin
OUT D1, D2, D3, D4, D5, D6 O Output pin, used to deliver power to the load
PD_DET G6 O Open drain output that allows user to sense when receiver is on transmitter surface
PGND A1, A2, A3, A4, A5, A6 – Power and logic ground
RECT C2, C3, C4, C5 O Filter capacitor for the internal synchronous rectifier
SCL E4 I SCL and SDA are used for I2C communication in bq5021. Ground if not needed. EN1 and EN2 are used in bq51020.
SDA F4 I
TERM F3 I Unused. Float in all WPC receivers
TMEM G5 O TMEM allows capacitor to be connected to GND so energy from transmitter ping can be stored to retain memory of state
TS/CTRL G4 I Temperature sense. Can be pulled high to send end power transfer (EPT – charge complete) to TX. Can be pulled low to send EPT – Overtemperature
VO_REG G1 I Sets the regulation voltage for output. Default value is 0.5 V
VTSB E5 I Voltage bias for temperature sense
WPG F5 O Open-drain output that allows user to sense when power is transferred to load
