EMG1130
Overview
1.1. General Description
The EMG1130 includes a controller that 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.
The device also includes a P/N gate-driver for 3-phase motor driving applications.
