MP6545数据手册MPS中文资料规格书

描述 Description

The MP6545 is a three-phase power stage IC designed to drive brushless DC (BLDC) motors or other loads.

The MP6545 operates across a 4.5V to 45V input voltage (VIN) range. It can deliver an output current (IOUT) up to 2.5A per phase, depending on the ambient temperature (TA) and PCB layout.

Internal safety and diagnostic features include over-current protection (OCP), input over-voltage protection (OVP), input under-voltage lockout (UVLO), and thermal shutdown.

The MP6545 has separate high-side (HS) and low-side (LS) input pins for each output pin. The MP6545 is available in QFN-28 (4mmx5mm) and TSSOP-28EP packages.
