Manual Reset

The manual reset input (MR) allows the user to trigger a

reset by using a push-button switch. The MR input is an

active low debounced input. By connecting a push-button

directly from MR to ground, the designer adds manual

system reset capability (see Figure 3). Reset is asserted if

the MR pin is pulled low to less than 100mV for 10µs or

longer while the push-button is closed. After MR is released,

released.

Using the ISL88016/17EVAL1Z Platform

The ISL88016/17EVAL1Z platform is provided with both an

ISL88016 in the top and an ISL88017 in the bottom

positions. Each IC is default programmed to VSET1, VSET2

and VSET3 = FLOAT but provided with jumpers to change

the Vth level by individually connecting the three VSET pins

VSET programming table for easy reference. Provide

Figure 4 for the ISL88016/17EVAL1Z schematic and

Figure 5 for its photograph.
