ADVANCE INFORMATION
In half-bridge control mode, each half-bridge gate driver can be individually controlled through the corresponding IN1, IN2 pins or through register. The DRVOFF signal has priority over the IN1 and IN2 signals. For half-bridge control, INx designates half-bridges. The DRV800x-Q1 internally handles the dead-time generation between high-side and low-side switching so that a single PWM input can control each half-bridge.
The half-bridges can be configured for SPI control with INx_MODE bits. When INx_MODE = 1b, the half-bridges can be enabled with S_INx bits.
The half-bridges can be set to the Hi-Z state individually through the S_HIZx bits. Both half-bridges can be simultaneously set Hi-Z with DRVOFF pin.
