In this mode, the corresponding input pin independently controls each high-side and low-side gate driver. This control mode allows for the external controller to bypass the internal dead-time handshake of the DRV835x or to utilize the high-side and low-side drivers to drive separate high-side and low-side loads with each half-bridge. These types of loads include unidirectional brushed DC motors, solenoids, and low-side and high-side switches. In this mode, If the system is configured in a half-bridge configuration, shoot-through occurs when the high-side and low-side MOSFETs are turned on at the same time.
Because the high-side and low-side VDS overcurrent monitors share the SHx sense line, using both of the monitors is not possible if both the high-side and low-side gate drivers are being operated independently.
In this case, connect the SHx pin to the high-side driver and disable the VDS overcurrent monitors as shown in Figure 24.
If the half-bridge is used to implement only a high-side or low-side driver, using the VDS overcurrent monitors is still possible. Connect the SHx pin as shown in Figure 25 or Figure 26. The unused gate driver and the corresponding input can be left disconnected.
