Document bl8092 in PDF form, 600 KB, filed among schematics. The file name contains only the part code, so the device and manufacturer are not indicated and the contents should be confirmed on opening. Files named after IC codes are usually datasheets with pin assignments, absolute ratings and reference circuits, useful for measuring a chip in circuit, checking its feedback network and finding a compatible substitute. Match the package and marking on the board before relying on pin numbers, since similar codes can have different pinouts.
