EMT1050
Overview
1.1. General Description
The EMT1050 integrates the 8051 core with peripheral circuits to perform Sine-Wave Field-oriented control (F.O.C.) of PMSM/BLDC motor applications. For rotor position detection, it support sensorless, Hall latch, Hall element, and BEMF input. In addition, system level peripheral functions, such as ADC, UART interface, IR decoder, watchdog timer, current sensing, short circuit protection (SCP) and locked-rotor protection are integrated to reduce ponent count, PCB size and system cost.
