Présentation

Description

ISL8491EIBZ-T is a Renesas/Intersil power-management IC in the ISL8491 family. It’s designed to regulate and supervise multiple rails in embedded/automotive applications. The device typically provides multi-rail regulator control, sequencing, and protective/fault-management features, with configurable outputs and a standard control interface. The EIBZ-T suffix denotes packaging/tape-and-reel options. For exact specs—input/output voltage ranges, current capability, efficiency, protection features, and pinout—refer to the official datasheet. If you share a datasheet link, I can give you a precise 180-word introduction tailored to that document.

Pinout

Pin count: 16 pins. Function: Isolated dual-channel digital isolator (transfers data across an isolation barrier, providing galvanic isolation between sides). The -T indicates tape-and-reel packaging; EIBZ is the package/variant code.

Manufacturer

Manufacturer: Renesas Electronics Corporation (Intersil brand). Intersil was acquired by Renesas in 2017, and Renesas now manufactures the device. Renesas is a Japanese multinational semiconductor company specializing in analog, power-management, and mixed-signal ICs.

Application

ISL8491EIBZ-T is used for isolated power-management applications. Typical areas include:
- Isolated DC-DC converters (flyback/forward) in telecom, data‑center, and industrial power supplies
- Automotive electronic systems (power rails, sensor interfaces)
- Medical devices requiring galvanic isolation
- Industrial automation and control equipment
- Portable/consumer electronics with isolated power stages
- Power-supply modules and chargers needing compact, efficient isolation
(Refer to the datasheet for exact topology and rating guidance.)

Package

ISL8491EIBZ-T uses an 8-pin Small Outline Integrated Circuit (SOIC-8) package, surface-mount, RoHS-compliant. The -T suffix indicates Tape-and-Reel packaging.
