BS_VX2

Boost Flying Capacitor Connection. Connect a VDRV rated ceramic capacitor

from BS_VX2 to BM_VX2 as close to the IC as possible for the high-side

MOSFET driver supply.

HS_VX2

High-Side Gate Driver Output. Driver output for the high-side MOSFET gate.

BM_VX2

Source Connection for High-Side MOSFET. Also serves as the return for the

high-side driver.

LS_VX2

Low-Side Gate Driver Output. Driver output for the low-side MOSFET gate.

BS_WY1

Boost Flying Capacitor Connection. Connect a VDRV rated ceramic

capacitor from BS_WY1 to BM_WY1 as close to the IC as possible for the

high-side MOSFET driver supply.

HS_WY1

High-Side Gate Driver Output. Driver output for the high-side MOSFET gate.

BM_WY1

Source Connection for High-Side MOSFET. Also serves as the return for the

high-side driver.

LS_WY1

Low-Side Gate Driver Output. Driver output for the low-side MOSFET gate.

BS_Y2

Boost Flying Capacitor Connection. Connect a VDRV rated ceramic

capacitor from BS_Y2 to BM_Y2 as close to the IC as possible for the high-

side MOSFET driver supply.

Note: Tie this pin to VDRV in case HS_Y2 is used to drive a low-side MOSFET

gate.

HS_Y2

High-Side Gate Driver Output. Driver output for the high-side MOSFET gate.

BM_Y2

Source Connection for High-Side MOSFET. Also serves as the return for the

high-side driver.

Note: Tie this pin to GND in case HS_Y2 is used to drive a low-side MOSFET

gate.

LS_Y2

Low-Side Gate Driver Output. Driver output for the low-side MOSFET gate.

GATE DRIVER

CSA

CSP0

Channel 0 current-sense amplifier positive analog input. Also serves as the

return for the low-side driver.

CSN0

Channel 0 current-sense amplifier negative analog input.

CSP1

Channel 1 current-sense amplifier positive analog input. Also serves as the

return for the low-side driver.

CSN1

Channel 1 current-sense amplifier negative analog input.

CSP2

Channel 2 current-sense amplifier positive analog input. Also serves as the

return for the low-side driver.

CSN2

Channel 2 current-sense amplifier negative analog input.

CSP3

Channel 3 current-sense amplifier positive analog input. Also serves as the

return for the low-side driver.

CSN3

Channel 3 current-sense amplifier negative analog input.
