BQ76952: FET driver IC necessity for high side switching with BQ76972

Part Number: BQ76952

Tool/software:

Dear TI Team,

Could you please support on following queries:

  1. Whether is there any EXTERNAL High side Gate driver IC required, if we go with high side MOSFET Switching. We observed in reference designs there is not any external driver, Directly from BQIC MOSFETS are driving in High side.
  2. What is the Drive current the BQIC Can support.
  3. Also, it has internal LDO’S(REG1, REG2). What is the current rating for these LDO’S.
