Temperature
The bq20z75-V180 has an internal temperature sensor and 2 external temperature sensor inputs TS1 and TS2
used in conjunction with two identical NTC thermistors (default are Semitec 103AT) to sense the battery
environmental temperature. The bq20z75-V180 can be configured to use internal or external temperature
sensors.
COMMUNICATIONS
The bq20z75-V180 uses SMBus v1.1 with Master Mode and package error checking (PEC) options per the SBS
specification.
SMBus On and Off State
The bq20z75-V180 detects an SMBus off state when SMBC and SMBD are logic-low for ≥ 2 seconds. Clearing
this state requires either SMBC or SMBD to transition high. Within 1 ms, the communication bus is available.
