Hi,
Can anyone help identify a Toshiba IC used for bidirectional control of a brushed motor? The original part number is partially missing as the chip has a crater blown in the package when the mechanism seized...
12-pin staggered SIL package, with metal heatsink tab Legend says TOSHIBA, part number begins TA80The IC is part of the controller for the power antenna in a 1998 Mazda
323F (known as a Miata in North America I believe). Toshiba don't list anything similar in their current line-up, so I'm assuming the IC is EOL and I'm looking at obsolete parts suppliers.If anyone can identify this chip and, better still, point me to a datasheet, I might be able to find a similar part or lash something up using discretes if I can't locate a replacement.
TIA
