current when V CC is out of tolerance. The DS1336 switches back to the higher current V CC from battery
current when PF and PF become inactive.
OPERATION
The required PF or PF input which controls the switching between the main V CC and backup battery can
be supplied by any of the devices listed in Table 1. All of the devices provide the DS1336 with a PF or
PF signal, switching between a main supply V CC and backup supply V BAT when V CC falls out of
tolerance. For applications requiring switching from the V CC supply inputs to V BAT , the required PF or
PF input to the DS1336 can be provided by the DS1236, DS1239, DS5001, or DS5340. For applications
requiring switching from the V CC inputs to the V BAT input when V CC begins falling out of tolerance, any
of the Dallas Semiconductor devices listed in Table 1 can provide the DS1336 with the required
switching input. A typical application is shown in Figure 1. For applications where switching between
V CC and V BAT must occur at a voltage level such that V CC is still greater than V BAT , the OUT5 pin is
recommended as it provides a diode path which will provide for a gradual transition between V CC and
V BAT . OUT5 can be tied to the other OUTPUT pins to provide a gradual transition for all five current
paths. In applications where tri-state switching is desired, OUT5 should be omitted. Only the PF/ PF pin
is required for switching. In cases where the PF input will not be used, it should be connected to GND.
When either PF or PF is active, either of the V BAT0X outputs is available, although they should not be tied
together (Figure 2, “DS1336 Block Diagram”). V BAT01 is recommended for sensitive applications such as
providing backup current to timekeepers, because its diode isolated path provides for increased
protection. V BAT02 is not recommended for applications where it would be tied to an OUTPUT pin
supplying a voltage greater than that of the backup battery because V BAT02 is not a diode isolated current
path.
