3 / 20 page Pin Descriptions (Continued) SW2 (Pin 16): Switch-node connection for Channel 2, which is connected to the source of the top MOSFET of Channel 2. It serves as the negative supply rail for the top-side gate driver, HDRV2. HDRV2 (Pin 17): Top-side gate-drive output for Channel 2. HDRV is a floating drive output that rides on the correspond- ing switching-node voltage. CBOOT2 (Pin 18): Bootstrap capacitor connection. It serves as the positive supply rail for the Channel 2 top-side gate drive. Connect this pin to VDD2 (Pin 19) through a diode, and connect the low side of the bootstrap capacitor to SW2 (Pin16). VDD2 (Pin 19): The supply rail for the Channel 2 low-side gate drive. Connected to VLIN5 (Pin 7) through a 4.7 Ω resistor and bypassed to power ground with a ceramic ca- pacitor of at least 1µF. Tie this pin to VDD1 (Pin 24). LDRV2 (Pin 20): Low-side gate-drive output for Channel 2. PGND (Pin 21): The power ground connection for both channels. Connect to the ground rail of the system. VIN (Pin 22): The power input pin for the chip. Connect to the positive (+) input rail of the system. This pin must be connected to the same voltage rail as the top FET drain (or the current sense resistor when used). LDRV1 (Pin 23): Low-side gate-drive output for Channel 1. VDD1 (Pin 24): The supply rail for Channel 1 low-side gate drive. Tie this pin to VDD2 (Pin 19). CBOOT1 (Pin 25): : Bootstrap capacitor connection. It serves as the positive supply rail for Channel 1 top-side gate drive. See CBOOT2 (Pin 18). HDRV1 (Pin 26): Top-side gate-drive output for Channel 1. See HDRV2 (Pin 17). SW1 (Pin 27): Switch-node connection for Channel 1. See SW2 (Pin16). RSNS1 (Pin 28): The negative (-) Kelvin sense for the internal current sense amplifier of Channel 1. See RSNS2 (Pin 15). www.national.com 3 |
