We have a battery powered device (16.8V lithium ion) with an on board microcontroller. If the battery falls below a critical level, as measured by the uC, it goes into sleep mode. We would also like a hardware low voltage protection circuit to prevent further discharge; ie 100% cutoff and zero current drain when the battery falls below 12 volts. The solar charging circuit needs to remain operation...
