PRODUCTION DATA.
The TS-CTRL pin offers three functions with one 3-state driver interface
Figure 31. 3-State Driver for TS-CTRL Note that the signals TERM and FAULT are given by two GPIOs. The truth table for this circuit is found in Table 7:
| TERM | FAULT | F (Result) |
|---|---|---|
| 1 | 0 | Z (Normal Mode) |
| 0 | 0 | End Power Transfer 0X00 |
| 1 | 1 | End Power Transfer 0X03 |
The default setting is TERM / FAULT = 1 / 0. In this condition, the TS-CTRL net is high impedance (high-z) and the NTC function is allowed to operate, normal operation. When TERM / FAULT = 1 /1 the TS-CTRL pin is pulled to GND and the RX is shutdown with End Power Transfer Over Temperature sent to TX. When TERM / FAULT = 0 / 0, the TS-CTRL pin is pulled to the battery and the RX is shutdown with End Power Transfer Unknown sent to the TX.
