5 Ld Voltage Supervisors with Adjustable Power-On Reset, Dual Voltage Monitoringor Watchdog Timer Capability The ISL88011 through ISL88015 family of devices offer bothfixed 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 ISL88013 and ISL88015 include awatchdog timer with a 51s startup timeout and a 1.6s normal timeout duration. On the ISL88011 and ISL88014, users can increase the nominal 200ms Power On Reset timeout delayby 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 resetoutputs are available on the ISL88011, ISL88012 and ISL88013 devices. All devices provide manual reset capability (see “Product Features Table” on page 4). Seven preprogrammed reset threshold voltages accurate to ±1.5% over temperature are offered (see “OrderingInformation” 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.
