RT7079 Datasheet | Richtek

® 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, munication interface, SVPWM, watchdog timer, current sensing, undervoltage-lockout (UVLO), short circuit protection (SCP)...
