概述

Description

ISL78419ARZ-T is a Renesas Intersil battery charge-management IC for Li‑ion/Li‑poly packs in portable devices. It combines a programmable Li‑ion charger with power-path management, monitoring, and safety features, all controllable via I2C/SMBus. Key functions include CC/CV charging, termination control, preconditioning, temperature sensing, and protections (overvoltage, overcurrent, thermal, faults). The ARZ-T suffix denotes the RoHS-compliant package in tape-and-reel form. Typical applications include smartphones, tablets, handheld devices, and other portable systems that require integrated charging and system-load management. For exact pinout, electrical specs, and application guidance, consult the official datasheet on Renesas’ website.

Package

QFN leadless package with exposed pad (4x4 mm footprint); Tape‑and‑Reel packaging (-T).

Pinout

- Pin count: 28-pin QFN (ARZ package), -T (tape-and-reel).
- Function: Automotive-grade power-management IC (PMIC) for DC-DC conversion; multi-rail buck/boost regulator controller (power-management regulator for generating core rails with protection features).

Manufacturer

- Manufacturer: Renesas Electronics Corporation (Intersil brand; Intersil’s assets were acquired by Renesas).
- What kind of company: A multinational semiconductor company specializing in analog, mixed-signal, and power-management integrated circuits (and related embedded solutions).

Application

ISL78419ARZ-T is a multi-rail, high-efficiency synchronous buck regulator for power management in computing and communications gear. Common applications:
- CPU/GPU core VRMs and memory rails
- PCIe power delivery
- FPGA/ASIC voltage rails
- Server/workstation motherboards and graphics cards
- Telecom/network equipment
- Embedded/battery-powered systems needing multiple outputs from a higher input voltage
