RT7079
Three-Phase PMSM/BLDC Motor Controller with Pre-Driver
General Description
Features
The RT7079 is an application specific IC designed for PMSM/BLDC motor applications. This two-in-one ASIC integrates several functional circuits, namely a 3-phase motor controller, a 3-phase gate driver, three bootstrap diodes, a 5V LDO regulator and a buck converter.
The RT7079 embeds the ARM 32-bit Cortex-M0 core with peripheral circuits to perform the sensorless with field oriented control (FOC). In addition, several system level peripheral functions, such as ADC, DAC, communication interface, SVPWM, watchdog timer, current sensing, undervoltage-lockout (UVLO), short circuit protection (SCP) and locked-rotor protection are integrated so as to reduce component count, PCB size and system cost.
