MP6543 - three-phase brushless DC motor driver

Description

The MP6543 family of products are all threephase brushless DC motor drivers.

They integrate three half-bridges, consisting of six Nchannel power MOSFETs, along with predrivers, gate drive power supplies, and currentsense amplifiers.

The MP6543 has ENABLE and PWM inputs for each ½-H-bridge.

Features

  • include thermal shutdown, under-voltage lockout (UVLO), and over-current protection (OCP). The MP6543, MP6543A, and MP6543B are available in a 24-pin, 3mmx4mm QFN package with an exposed thermal pad.

DESCRIPTION The MP6543 family of products are all threephase brushless DC motor drivers. They integrate three half-bridges, consisting of six Nchannel power MOSFETs, along with predrivers, gate drive power supplies, and currentsense amplifiers. The MP6543 has ENABLE and PWM inputs for each ½-H-bridge. The MP6543A has separate high-side and low-side inputs, while the MP6543B has Hall-element inputs. Otherwise, they are similar. References to the MP6543 in this document apply to the other parts, unless otherwise noted. The MP6543 is able to deliver up 2A continuously (depending on thermal and PCB conditions), with the adjustable over-current protection threshold.
