DESCRIPTION  
The DS1239 MicroManager provides all the necessary functions for power supply control and  
monitoring, reset control, and memory backup in microprocessor-based systems. Using the DS1239, an  
AC power switch is no longer required for microprocessor-based systems. A keyboard control system for  
power supply start up and shutdown is provided through the use of the Power Supply Control Input and  
Output. In other respects, the DS1239 is functionally identical to a DS1236 in the NMOS mode. For a  
complete description of the other DS1239 features, refer to the DS1236 data sheet. Pin-out of the
