Pins

Name

Type

Function

GH_BRG2

Output

Gate driver output for the high-side FET of half bridge 2. Connect this pin to a series 12Ω

resistor to the respective bridge FET gate.

BST_BRG2

Input

Bootstrap pin for half bridge 2. Tie an external capacitor from this pin to the SW_BRG2

pin to generate a drive voltage higher than the input voltage.

SW_BRG2

Output

Switch node for half bridge 2.

GL_BRG2

Output

Gate driver output for the low-side FET of half bridge 2. Connect this pin to a series 12Ω

resistor to the respective bridge FET gate.

GL_BRG1

Output

Gate driver output for the low-side FET of half bridge 1. Connect this pin to a series 12Ω

resistor to the respective bridge FET gate.

SW_BRG1

Output

Switch node for half bridge 1.

BST_BRG1

Output

Bootstrap pin for half bridge 1. Tie an external capacitor from this pin to the SW_BRG1 to

generate a drive voltage higher than the input voltage.

GH_BRG1

Output

Gate driver output for the high-side FET of half bridge 1. Connect this pin to a series 12Ω

resistor to the respective bridge FET gate.

DRV_VIN

Input

Input power supply for the internal gate drivers. Connect a 10μF capacitor from this pin to

ground.

VBRG_IN

Input

Bridge voltage input sense.

VDEM1

Input

High-pass filter input. Voltage demodulation pin for data packets based on coil voltage

variation; transmitted by power receiver.

IDEMI

Input

High-pass filter input. Current demodulation pin for data packets based on coil current

variation; transmitted by power receiver.

ISNS_OUT

Output

Input current sense output.

CSN

Input

Low-side input current sense (VBRIDGE).

CSP

Input

High-side input current sense (VIN).
