The ISL88011, ISL88012, ISL88013, ISL88014, ISL88015 family of devices offer both fixed and/or adjustable voltage-monitoring that combine popular functions such as Power-On reset control, watchdog timer, supply voltage supervision, and manual reset assertion in a small 5 Ld SOT-23 package.Unique features on the ISL88013IH523Z-TK and ISL88015 include a watchdog timer with a 51s start-up timeout and a 1.6s normal timeout duration. On the ISL88011 and ISL88014, users can increase the nominal 200ms Power-On reset timeout delay by adding an external capacitor to the CPOR pin. Both fixed and adjustable voltage monitors are provided by the ISL88012. Complementary active-low and active-high reset outputs are available on the ISL88011, ISL88012 and ISL88013IH523Z-TK devices. All devices provide manual reset capability (see “Product Features Table” on page 5).Seven preprogrammed reset threshold voltages accurate to ±1.5% over temperature are offered (see “Ordering Information” on page 3). The ISL88012, ISL88014 and ISL88015 have a user-adjustable voltage input available for custom monitoring of any voltage down to 0.6V. All parts are specifically designed for low power consumption and high threshold accuracy.
