The Power Ranger module features the MAXIM MAX1614 high-side NMOSFET switch driver that provides power switching control using two digital signals. The module's size makes it very useful in portable battery-powered applications but it can be used with continuous DC power sources or voltage regulators as well. The module allows for push-button on/off control with very low current consumption. Additionally, the module has an accurate low-battery detector that can be used to,
The C++ library and examples provided on GitHub allows one to use the Power Ranger to,
Debouncing of the module's tactile switch must be performed via software. Reference code may be found in the manual_shutdown_init function of BSP.cpp. There is no switch debouncing hardware on the modules because the module push-button is connected directly to the /ON signal of the MAX1614. The signal must be pulled up to an internal +8V rail when the part receives power at its input. This process may require that specific timing requirements internal to the device must be met in order for the MAX1614 to turn on properly. Additionally, the /ON pin of the MAX1614 is meant to source minimal current; overloading this pin may cause the part to malfunction. Switch debouncing hardware connected to the /ON signal of MAX1614 may affect critical timing requirements and or overload the device, therefore debouncing hardware was not included.
The following table provides insight on how to control the output power (OUT+) of the module:
