P1/13 3-Phase Motor Driver IC ECN30671SP/SPV/SPR The ECN30671 is a 3-Phase Permanent Magnet Synchronous Motor and Induction Motor

P1/13 P1/13 3-Phase Motor Driver IC ECN30671SP/SPV/SPR ECN30671SP/SPV/SPR The ECN30671 ECN30671 is a 3-Phase Permanent Magnet Synchronous Motor and Induction Motor driver. The chip integrates Top and Bottom arm drive circuits controlled by 6CMOS inputs, six (6) 500V rated IGBTs. To reduce motor current losses, a PMSM can now be driven directly from rectified 220VAC 220VAC (up to 450VDC 450VDC) power lines, or from any DC power bus down to 15VDC 15VDC. Description · Integrated 3-Phase 6-IGBT Motor Bridge with on chip Free-Wheeling diodes. · Maximum Ratings 500VDC/3 500VDC/3.0A · Latch-Up free monolithic IC built with a high voltage Dielectrically Isolated (DI) process. · Available in 3 package types with built-in heat sink (Tab). Functions and Features · PWM control of Top and Bottom arm IGBTs is possible with a Microprocessor. · On-Chip 7.5VDC regulator (CB) with a guaranteed external Max load (25mA). · Over-Current protection is set by an external Sense Resistor (RS). · Under-Voltage protection for Top and Bottom IGBT Arms. · Top and Bottom arm IGBTs can operate in 20kHz chopping frequency. · 6 Logic inputs are compatible with 5V CMOS or LSTTL outputs.
