International ClassH02J 007/14Foreign Application Priority Data1988-07-07 JPAbstractA reference voltage circuit for a voltage regulator control includes three parallel voltage dividers cross-coupled by oppositely poled diodes, one of the dividers having a negative voltage-temperature characteristic tied to the battery electrolyte temperature and another divider having a positive characteristic. With this arrangement the reference voltage remains constant below a first electrolyte temperature t1, decreases between t1 and a second, higher temperature t2, and decreases at a reduced rate above t2. | |
