I've used the TPIC6A595 (350mA per output) with zero problems. I've tried short circuit to +12V and GND and they just keep on going, 400+ units in service with no reported failures (touch wood). Good PCB layout is said to be important though. -- Brent Brown, Electronic Design Solutions 16 English Street, Hamilton, New Zealand Ph/fax: +64 7 849 0069 Mobile/txt: 025 334 069 eMail: brent.brown@clear.net.nz -- http://www.piclist.com#nomail Going offline?
