Applications Information
Output Tracking and Sequencing
The MIC2585 is equipped with optional supply
settings: Tracking or Sequencing. There are many applica-
tions that require two supplies to track one another within a
specified maximum potential difference (or time) during power-
up and power-down, such as in switching a processor on and
off. In many other systems and applications, supply sequenc-
ing during turn-on may be essential such as when a specific
circuit block (e.g., a system clock) requires available power
before another block of system circuitry. For either supply
configuration, the MIC2585 requires only one additional
component and can be used as an integrated solution to
traditional, and most often complex, discrete circuit solutions.
Additionally, the two optional supply settings may be com-
bined to provide supply sequencing during start-up and
supply tracking during turn-off (see Figure 6 below). The
MIC2585 guarantees supply tracking within 250mV for power-
up and power-down independent of the load capacitance of
each supply. See "Figure 2" of the "Timing Diagrams".
Wiring the TRK pin to either OUT1 or OUT2 of the MIC2585
enables the tracking feature. The OUT1 and OUT2 pins
provide output track sensing and are wired directly to the
output (source) of the external MOSFET for Channel 1 and
Channel 2, respectively.
The MIC2584/85 can also be used in systems that support
more than two supplies. Figure 7 illustrates the generic use
of two separate controllers configured to support four inde-
pendent supply rails with an associated output timing re-
sponse. The PG (or /POR) output of the first controller is used
to enable the second controller. As configured, a fault condi-
tion on either V
OUT1
or V
OUT2
will result in all channels being
shut down. For systems with multiple power sequencing
requirements, the controllers output tracking and sequenc-
ing features can be implemented in order to meet the systems
timing demands.
