PRODUCTION DATA
The device has three power modes plus an POR state.
The various functions supported under different power modes are summarized in Table 9-34 and the power state diagram is shown in Figure 9-59.
| Functional Block | SHUTDOWN | SLEEP | ACTIVE | POR |
|---|---|---|---|---|
| Main ADC | √ | This is not a power state. All circuits are off. A sufficient voltage on VBAT will POR the device and put it to SHUTDOWN mode | ||
| AUX ADC | √ | |||
| OV/UV protector | √(1) | √ | ||
| OT/UT protector | √(1) | √ | ||
| Cell Balancing | √(1) | √ | ||
| OTCB Detection | √(1) | √ | ||
| Module Balancing (via control through MB_TIMER_CTRL) | √ | |||
| UART | √ | |||
| Comm Vertical Communication | √ | |||
| Fault Status and NFAULT Communication | √ | √ | ||
| Comm timeout | √ | |||
| SLEEP timeout | √ | |||
| Thermal Shutdown Detection | √ | √ | ||
| SPI Master | √ | |||
| OTP programming | √ | |||
| Always-on block to detect POR of the device | √ | √ | √ |
