X80130/31/32/33/34 – Preliminary Information
inputs to the X80130. The ViMON inputs monitor the
voltage to make sure it has reached the minimum desired
level. When each voltage monitor determines that its input
is good, a counter starts. After the programmed delay time,
the X80130 sets the ViFAIL signals LOW. The ViFAIL
signals can be wire ORed together and tied to an interrupt
on the microcontroller. Any individual voltage failure can be
viewed in the Fault Detection Register.
In the factory default condition, each voltage monitor is
instructed to go LOW 100ms after the the input voltage
reaches its threshold. However, each ViFAIL delay is
individually selectable as 100ms, 500ms, 1s and 5s. The
delay times are chaged via the SMBus during calibration of
the system.

Power Up of Supplies Via Relay Sequencing Using Voltage
Monitors (see Figure 10 and Figure 9).
Several power supplies and their respective power up start
times can be controlled using the X80130 such that each of
the power supplies will start in a relay sequencing fashion.
In the following example, the 1st supply is allowed to power
up when the input regulated supply reaches an acceptable
threshold. Subsequent supplies power up after the prior
supply has reached its operating voltage. This configuration
ensures that each subsequent power supply turns on after
the preceding supplies voltage output is valid. Again, the
X80130 offers programmable delays for each voltage
monitor and this delay is selectable via the SMBus during
calibration of the system.
