BQ79718-Q1: Questions on the Pre-Production datasheet

Part Number: BQ79718-Q1

Hi there, 

We are currently designing in the BQ79718-Q1 in our product. However, there are a few things in the datasheet that are questionable or inconclusive for us. 

Please reach out via email as soon as possible to get our questions answered. We are running from the December 2022 version, revision (*), Notes >> BQ79718-Q1 Advance Information Release. 

Questions are around:

  1. Table 6-1 Pin Functions; specifically on the description for TSREF.
  2. Figure 9-6 and how it relates to our lower count cell stack configuration (see section 9.2.1.2.3 Unconnected Cells). It has (3x) figures, but we're not sure which one applies.
  3. Figure 8-19, Figure 9-5 and Section 9.2.1.2.2.3 Cell Balancing with External FETs, especially around the purpose of CHP and guidance on sizing (voltage, Vgs, Cgs, etc.) for that circuit. 

Regards,

Joel H
