The ISL88031 is a five-voltage monitor with industry-leading reset threshold accuracy and low power consumption. The device provides a variety of common features such as power-on reset, undervoltage supply monitoring, reset signaling and manual reset. The ISL88031 uses a small 8-pin MSOP package to monitor up to 5 different voltage levels, which can help reduce system costs, reduce board space requirements and improve system reliability.
The ISL88031 is a five‑voltage monitor IC offered in an 8‑lead MSOP package. It provides five independent voltage reference outputs (Vpp, V2MON, V3MON, V4MON, V5MON) with low quiescent current, making it suitable for power‑management and monitoring applications.
The datasheet includes electrical characteristics, maximum ratings, pin configuration, package dimensions, and typical application circuits, along with an evaluation board description for system integration. This manual is written in Japanese.
