ISL88013: 5 Ld Voltage Supervisor with Watchdog Timer Capability and Active-High Reset

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 ISL88013 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 CPORpin. 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 ISL88013 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.
