The ISL88011 through 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.
The ISL88011‑ISL88015 family provides low‑power voltage supervision, power‑on‑reset (POR), watchdog timer and manual reset functions. Devices are offered in a 5‑lead SOT‑23 package with ultra‑low 5.5 µA supply current.
Key features include fixed and adjustable voltage thresholds, dual‑voltage monitoring, active‑low and active‑high reset outputs, and optional POR timeout adjustment via an external capacitor. The family is suited for process control, embedded systems, portable equipment and other applications requiring reliable power‑up sequencing and brown‑out protection.
| Supply Voltage Range (Vop) | 2.0 V – 5.5 V |
|---|---|
| Watchdog Timer Startup Timeout | 51 s |
| Watchdog Timer Normal Timeout | 1.6 s |
| Default POR Timeout | 200 ms |
They are supplied in a 5‑lead Small Outline Transistor (SOT‑23‑5) package.
Seven pre‑programmed reset threshold voltages are offered.
