ZHCS926C May 2012 – May 2021 BQ34Z100
PRODUCTION DATA
The BQ34Z100 can measure temperature via the on-chip temperature sensor or via the TS input, depending on the setting of the [TEMPS] bit PackConfiguration(). The bit is set by using the PackConfiguration() function, described in Section 7.2.2.
Temperature measurements are made by calling the Temperature() function (see Section 7.2.1.1 for specific information).
When an external thermistor is used, REG25 (pin 7) is used to bias the thermistor and TS (pin 11) is used to measure the thermistor voltage (a pull-down circuit is implemented inside the device). The device then correlates the voltage to temperature, assuming the thermistor is a Semitec 103AT or similar device.
