... Manual Reset assertion in a small 6 Ld TSOT-23 package. By connecting the three VSET pins to V users can program the voltage trip point from 1.60V to 2.85V in 50mV increments on the ISL88016 and from 2.15V to 4.65V in 100mV increments on the ISL88017. These user- selectable reset threshold voltages are accurate to ±2% over temperature and the reset signal is valid down to 1V. Intersil’ ...

... RST POR FIGURE 1. VOLTAGE MONITORING TIMING DIAGRAM Power-On Reset (POR) Applying power to the ISL88016 and ISL88017 activates a POR circuit which asserts reset once V goes LOW). This provides several benefits: • It prevents the system microprocessor from starting to operate with insufficient voltage. • It prevents the processor from operating prior to stabilization of the oscillator ...

... FIGURE 3. CONNECTING A MANUAL RESET PUSH-BUTTON 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 to either V (1) or GND (0) ...
