The DRV2901 does not require a power-up sequence. The outputs of the H-bridges remain in a high­impedance state until the gate-drive supply voltage (GVDD_X) and VDD voltage are above the undervoltage protection (UVP) voltage threshold (see the Electrical Characteristics section of this data sheet). Although not specifically required, it is recommended to hold RESET_AB in a low state while powering up the device. This allows an internal circuit to charge the external bootstrap capacitors by enabling a weak pulldown of the half-bridge output.
