Microprocessor power will not return until the battery has
recharged to a voltage greater than HTH+ (Figure 6).
The MAX6430/MAX6431/MAX6432 and MAX6436/
MAX6437/MAX6438 dual-output battery monitors can
be used in conjunction with a battery charger to pro-
vide a system with additional information about the bat-
tery charge state (Figure 10). Many battery chargers,
such as the MAX1879, provide the user with a CHG
output, which tells the system that the battery is
charged. The MAX6430/MAX6431/MAX6432 and
MAX6436/MAX6437/MAX6438 dual-output battery mon-

itors provide two outputs, which can be used to relay
the battery condition to the system. This information is
useful in determining which system resources can be
powered by the battery at the current charge state.
