Power management

We use the LD1117 and we notice that the Rthja is higher for the SOT-223 that the SO-8; it seems counter intuitive since the SOT-223 is looking more a power package than the SO-8. Please explain? Denis Lachapelle eng. Cysca.ca

How to munt and cool D2PAK IGBT in power bridge

I want to use  STGB8NC60KDT4 IGBT, 15 A 600 V, 3-Pin D2PAK (TO-263)in a motor controlpower bridge, The bridge will be running at 300VDC and about 3-5 amps. At this power there will be 6-12 watts dissipated in the IGBT.I would like to cool them by scr...

We use the VNH3SP30 H-bridge motor driver for an application where we need to drive a motor with peak currents over 30A. The PCB layout are made following the recommendations from datasheet. But the H- bridge die when running the motor. Any help?

Is external protection needed?And what type off protection if it also should be able to handle EMC Burst and Surge pulses?

I have problems to setup a communication over I2C with my MCU and a STWLC33 on a STWLC33JRF eval board. The data sheet of the STWLC33 has errors. See details.

Chapter 8.5 says write the register value as two bytes (Low and High), but all pictures and descriptions later sends only one byte for the register value. Whats correct?If I send START ADR(WRITE) REG START ADR(READ) VALUE STOP the ADR byte is acknowl...

Your workshop, "Putting the right spin on Stepper and Brushless DC motors", in Santa Clara couple days ago was full, so I couldn't get in. But can I get the workshop materials?

Would appreciate getting copies of the briefing slides, list of HW and SW used, and installation/setup instructions. Thanks,Mike
