Figure 82. VMx Voltage Window Comparator

The warning and fault threshold windows are programmable

through the VMx_WARN_WINDOW bits and VMx_FAULT_

WINDOW bits in the WARN_WINDOW and FAULT_

WINDOW SPI registers. The programmable range is from 4%

to 8%, as shown in Table 24 and Table 25, with a fixed hysteresis.

These threshold windows are referenced to 600 mV. See Table 1

for the detailed specification.

The blank time of the VMx pin is programmable through the

VMx_BLANK_TIME bits in the VOLTAGE_BLANK_TIME0

SPI register. The programmable range is from 16 µs to 352 µs

with 48 µs as the default, as shown in Table 26.

MODE PIN SETTING

The ADP5140 has a MODE pin to set different functions with

different resistances between the MODE pin and ground. Three

functions are available: debug mode setting, device index

setting, and VIO selecting. Table 27 shows the relationship of the

resistance between the MODE pin and ground (RMODE) and the

function settings.
