... TOSHIBA BiCD Integrated Circuit Silicon Monolithic DC Motor Driver The TB6557FLG is a driver IC for driving DC motors. Its employs LDMOS devices with low ON resistance for output drive transistors. The TB6557FLG incorporates two constant current-controlled H-bridge drivers and four voltage-controlled H-bridge drivers, making it ideal for controlling Zoom/AF/IRIS lens motors in digital still cameras and camcorders ...

... When mounting or soldering, take care to ensure that neither static electricity nor electrical overstress is applied to the IC (measures to prevent anti-static, leaks, etc.). • When incorporating into a set, adopt a set design that does not apply voltage directly to the island section.

... Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. 14 TB6557FLG 2006-6-26 ...
