Overview
® RT7080 Integrated Power Module for PMSM/BLDC Motor Driver General Description Features The RT7080 is a highly integrated power module designed for advanced motor drive applications.
This module integrates an ARM-base motor controller, a 3-phase gate driver, six MOSFETs, a 5V LDO, a charge pump circuit, a buck converter and three current sense resistors, those circuits are specifically implemented for PMSM/BLDC motor applications.
For main control scheme, the RT7080 integrates an ARM 32-bit Cortex-M0 core with peripheral circuits to perform field oriented control (FOC) and sensorless motor control.
In additions, 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 fully integrated so as to reduce component count, PCB size and system cost.
Furthermore, the RT7080 drives internal N-Channel MOSFETs in a configuration of three half-bridges with a built-in charge pump circuit up to 28V.
With these designs, the RT7080 therefore offers great benefits to users such as cost effectiveness, easy design, board space saving, production flexibility and better quality control.
The RT7080 is available in WQFN-40L 6x6 packages.
