GH_B 38 O Gate drive output for High-Side MOSFET, half-bridge B BST_B 39 P Bootstrap cap pin for half-bridge B SL_A 40 I Low-Side MOSFET source connection, half-bridge A. Low-side VDS measured between this pin and SH_A. GL_A 41 O Gate drive output for Low-Side MOSFET, half-bridge A SH_A 42 I High-Side MOSFET source connection, half-bridge A. High-side VDS measured between this pin and PVDD. GH_A 43 O Gate drive output for High-Side MOSFET, half-bridge A BST_A 44 P Bootstrap cap pin for half-bridge A VDD_SPI 45 I SPI supply pin to support 3.3V or 5V logic. Connect to either 3.3V or 5V. GND 46, 47, O GND pin. The exposed power pad must be electrically connected to ground plane through soldering to (POWER PAD) 48, 49 PCB for proper operation and connected to bottom side of PCB through vias for better thermal spreading. 4 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DRV8303 |
