Can Allegro bend the leads under the package or outward, so that I can surface-mount the ACS750?
In order to safely conduct 100 A currents, the power leadframe in the ACS750 has been constructed with a relatively heavy gauge. Because of this heavy gauge, the terminal leads are not very flexible. If the ACS750 is surface-mounted, small amounts of board flex, or the action over time of thermal expansion and contraction, would break the IC off the board. Allegro does not believe surface-mounting is practical for this device.
