EMT1042
Overview
1.1. General Description
The EMT1042 integrates the 8051 core with peripheral circuits to perform sine-wave motor control. For rotor position detection, it can support sensorless motor or Hall latch IC input. In addition, system level peripheral functions, such as ADC, OPAMP, parator, munication interface, SVPWM, watchdog timer, current sensing, undervoltage-lockout (UVLO), over current protection (OCP) and locked-rotor protection are integrated to reduce ponent count, PCB size and system cost.
