The MAX17601 supports higher current through parallel operation of dual drivers like other competing devices.
Both inputs, INA and INB, must be shorted together in the PCB layout as close to the MAX17601 as possible.
Both outputs OUTA and OUTB must be shorted together in the PCB layout as close to the MAX17601 as possible. This will minimize the mismatching between the 2 channels due to PCB layout parasitics.
