DESCRIPTION
The MP6546 supports multi-slave mode and allows three-axis gimbals to be connected to a single I2C interface to reduce the microcontroller (MCU) load and system cost. The MP6546 can deliver up to 3A of peak current. It uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs (HS-FETs). Internal safety features include thermal shutdown, under-voltage lockout (UVLO), overcurrent protection (OCP), short-circuit protection (SCP), and over-voltage protection (OVP). The MP6546 is available in a QFN-20 (3mmx4mm) package with an exposed thermal pad. MP6546 22V, 3A, Peak, 3-Phase BLDC Driver with 1MHz I2C InterfaceFEATURES
