Edge710

Application Information

Super Voltage Operation

The Edge710 may be used to generate a super voltage

level up to 13V at the driver output. To generate this high

voltage, an analog input mux may be used to switch

between the normal high and low drive levels, and a super

voltage level.

Certain Power Supply conditions must be met to support

this functionality.

Extremely Low Leakage Usage

The Edge710 is capable of supporting total load + drive

+ comparator leakage

≤ ~15 nA. This low leakage mode

may be very useful during PMU operation if the pin

electronics are not isolated by a relay, thus eliminating

the need for 1 relay per pin.

To realize this low leakage, the following conditions must

be met:

1. IPD_D = 1 (place the driver in "power down" mode)

2. IPD_C = 1 (place the comparator in "power down"

mode)

3. CVA, CVB

≥ VINP (program the comparator

thresholds

≥ any expected voltage at the comparator

inputs.)
