Figure 4. This screen capture illustrates how to configure the MAX6876 for mixed-mode

tracking/sequencing.

7. Consult Table 1 and select the appropriate options for each channel.

Table 1. Channel-Control Options.

Option

Name

Function

100 Ohm

Pull Down

Activates a 100Ω pulldown resistor on the channel's OUT connection during shutdown only.

Overcurrent

Threshold

Activates overcurrent monitoring on the channel. This compares the IN_ voltage to the OUT_

voltage. When OUT_ falls below a percentage of IN_, Overcurrent Threshold asserts the OC

output (bringing it low).

Assert

RESET

Activates this channel's control over the RESET line. If this channel falls below its power-

good threshold, RESET asserts low.

Power

Good

Threshold

When the channel's OUT voltage is within this percentage of the IN voltage, the

corresponding PG pin asserts (goes high impedance).
