RSV

Output

Reserved for internal use. Do not connect.

29

GPIO

I/O

General purpose digital I/O pin.

30

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.

31

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.

32

SW_BRG2

Output

Switch node for half bridge 2.

33

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.

35

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.

36

SW_BRG1

Output

Switch node for half bridge 1.

37

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.

38

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.

39
