Allegro MicroSystems, LLC Introduces New Quad DMOS Full Bridge PWM Motor Driver IC
2017-07-18 | ReturnInternal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. To minimize power consumption when not in use, the A5990 can be put into a low current Sleep Mode. Protection features include thermal shutdown with hysteresis, undervoltage lockout (UVLO), over current (OCP) and crossover-current protection. Special power-up sequencing is not required.
The A5990 is supplied in an EV package, a 6 mm × 6 mm, 40-pin QFN package with a nominal overall package height of 0.90 mm. The package is lead (Pb) free, with 100% matte-tin leadframe plating. It is targeted at the dual axis multiple motor systems including CCTV (pan and tilt), 3D printing, point of sale (receipt and lotto printers), office automation (laser printers, copiers, etc.), medical (diagnostic systems), and the industrial automation market (ATMs and pick and place machines).
