The device features four modes: NORMAL, SLEEP, DEEPSLEEP, and SHUTDOWN. The first is used to operate at the highest performance and power usage when large loads are applied. SLEEP is best used on lighter loads where the risk of things going wrong are lower. DEEPSLEEP is optimized for keeping an MCU powered but little else, providing a very low energy usage. SHUTDOWN is the lowest energy consumption mode that is an excellent choice for long-term storage.
- NORMAL Mode: All protections are enabled, both CFETs and DFETs can be on, constant voltage, current, and temperature measurements, with the LDO enabled and programmable.
- SLEEP Mode: Most protections enabled, DFET on but not the CFET, ADC has intermittent sampling, the LDO still runs, and the device can leave SLEEP mode by rising current, communication, a charger, or a reset signal.
- DEEPSLEEP Mode: Most circuits off, FETs off, no ADC or CC sampling, no protection features enabled, LDO still operates, and the mode can be exited by communication, chargers, or the reset signal.
- SHUTDOWN Mode: All circuity is off except the wakeup detector, no measurements or protections, the LDO is disabled, and the device can exit the mode by being pulling TS2 to GND or attaching a charger.
