MP6543H - Three-Phase Power Stage

General Description

The MP6543H family of products (MP6543H, MP6543H-A, and MP6543H-B) are three-phase brushless DC motor drivers.

They integrate three half-bridges, consisting of six N-channel power MOSFETs, as well as pre-drivers, gate drive power supplies, and current-sense amplifiers.

Key Features

  • include thermal shutdown, under-voltage lockout (UVLO), and over-current protection (OCP). The MP6543H is available in a QFN-24 (3mmx4mm) package with an exposed thermal pad. MP6543H 22V, 2A, Three-Phase Power Stage.

DESCRIPTION The MP6543H family of products (MP6543H, MP6543H-A, and MP6543H-B) are three-phase brushless DC motor drivers. They integrate three half-bridges, consisting of six N-channel power MOSFETs, as well as pre-drivers, gate drive power supplies, and current-sense amplifiers. The MP6543H has enable (EN) and PWM inputs for each half-bridge. The MP6543H-A has separate high-side (HS) and low-side (LS) inputs, while the MP6543H-B has Hall-effect sensor inputs. Otherwise, these three devices are similar. References to the MP6543H in this document apply to the MP6543H-A and MP6543H-B, unless otherwise noted. The MP6543H delivers up to 2A of continuous current (depending on thermal and PCB conditions) with an adjustable over-current protection (OCP) threshold.
