BQ76PL455A-Q1: 电池断线检测 BQ76PL455A-Q1

Part Number: BQ76PL455A-Q1

你好:

BQ76PL455ATPFCTQ1电池断线检测资料中比较模糊,

断线检测设置前后的比较值多少?有没有界定?谢谢!!!

  • 您好,正在询问更了解这款芯片的TI工程师,再帮您解答,稍后回复。

  • 您好 ,There is a Squeeze function in BQ76PL455A-Q1 that helps to detect open sense wire conditions. Enabling Squeeze function turns on a 5k Ohm resistor across adjacent VSENSE pins and creates additional voltage drop through the 100 Ohm resistors in series with the VSENSE pins.
    This causes an increase in the voltage applied to the window-comparator blocks above and below the inputs that
    have the Squeeze resistor applied. To enable the Squeeze function, set TSTCONFIG[EQ_SQUEEZE_EN] =1.
    Please refer to BQ76PL455A-Q1 datasheet section 7.3.12.8.1 for more details of an example and block diagram.
