isl88016, isl88017 fn6141 rev 1.00 page 5 of 8 august 5, 2015 principles of operation the isl88016 and isl88017 devic es provides a low cost solution for those voltage moni toring applications needing supply voltage supervision wit h power reset control, and manual reset assertion. by integrating these common features along with three pins of vth programming into a small 6 ld tsot-23 package and using only 1a of supply current, the isl88016 and is l88017 devices can lower system cost, reduce board space requirements, and increase the reliab ility of a system while reducing inventory overhead costs. low voltage monitoring during normal operation, the isl88016 and isl88017 monitor the voltage level of v dd . the device asserts a reset (rst = low) if this voltage is less than the programmed voltage trip point. the re set signal prevents system operation during a power failure o r brownout condition. this reset signal remains asserted until v dd exceeds the voltage threshold setting for the reset time delay period t por . (see figure 1). the isl88016 and isl88017 allo w users to customize the power-on reset voltage threshold level, which is the voltage at which the reset i s deasserted. the th ree vset inputs are either tied to v dd , gnd or left open to program v th . see the power-on reset voltage se tting table on page 3 for specific voltage configuratio n. also see figure 2 for a schematic representation of the vset pins being programmed, noti ng the minimum necessary components for ic operation. do not a ttempt to reprogram a v th while the ic is biased. power-on reset (por) applying power to the isl88016 and isl88017 activates a por circuit which a sserts reset once v dd = 1 v. (i.e., rst goes low). this provides several benefits: ? it prevents the system micropr ocessor from starting to operate with insuff icient voltage. ? it prevents the processor from operating prior to stabilization of the oscillator. ? it ensures that the monito red device is held out of operation until internal reg isters are properly loaded. ? it allows time for an fpga t o download its configuration prior to initializat ion of the circuit. the reset signal remains asserted until v dd rises above the minimum voltage sense le vel for time period t por . this ensures that the v dd voltage has stabilized. optional v dd de-coupling capacitance can be added to filter transients if needed. figure 1. voltage monitoring timing diagram v dd mr v th / v por 1v >t mr rst t por t por t por t rst isl88016 vset1 isl88017 figure 2. setting v por using vset inputs vset2 vset3 gnd v dd rst /mr
