Help Identifying Touch Controller Chip


My oven started displaying an error code E11 that indicates a "shorted key".
These chips are on the back of the oven touch panel. They don't seem to be the Atmel chips. The marking on the SOT23-6 packages is B2PE.
Any info would be appreciated.

A bit of hunting finds that it's a TouchSensor TS-100.
