PRODUCTION DATA
The device is configured to a simpler HOT/COLD function only. Two temperature thresholds are monitored: the cold battery threshold, and the hot battery threshold. These temperatures correspond to the VCOLD and VHOT thresholds in the Electrical Characteristics table. Charging and safety timers are suspended when VTS < VHOT or VTS > VCOLD.
For devices where the TS function is not needed, tie a 10-k? resistor to the TS/MR pin.
There is an active voltage clamp present on this device which will prevent the voltage on TS/MR pin from rising above the VTS_CLAMP threshold. This will particularly be ON when the TS/MR pin is floating.
When the button is detected as a “press” during the charging process, charging will be momentarily suspended till the button is high again. When charging is disabled in any of the TS faults, the trickle charging is also disabled.
