BL8305A BALLAST CONTROL IC The ballast control IC BL8305A is an improved version of the BL8301.

The BL8305A provides more functionality and is easier to use than previous IC BL8301.

The BL8305A optimizes the compatibility of driving MOSFET half-bridge (MHF) or Bipolar half-bridge (BHF).

Especially for Bipolar half-bridge, the BL8305A can automatically adjust the base current intensity (BCI Auto-Adj), and guarantee that the half-bridge is in the optimum condition and reduces the power loss of ha
