Descripción general

Description

ISL94203IRTZ-T is a lithium‑ion battery protection IC from Intersil/Renesas used in multi‑cell battery packs. It monitors the voltages of individual cells and the pack temperature, and it drives external MOSFETs to disconnect the pack if a fault occurs. The device provides protection against overcharge, overdischarge, overcurrent, and short‑circuit events, and it reports fault/status information to a host controller. It is designed for multi‑cell stacks (commonly 3–4 cells) and is used with external current sense and MOSFETs; it does not perform active cell balancing. Packaging suffix “-TZ‑T” indicates tape & reel packaging. For exact cell count, voltage/current ranges, timing, fault modes, and pinout, consult the ISL94203 datasheet and packaging documents. Typical applications include BMS circuitry for Li‑ion packs in consumer electronics, power banks, cordless tools, and other portable devices.

Features

ISL94203IRTZ-T is a Li‑ion battery monitor/protector IC for multi-cell packs (typically 2–8S). Core features include:
- Per‑cell voltage sensing (up to 8 cells) with rapid fault detection
- Overvoltage and undervoltage protection for each cell
- Overcurrent/short‑circuit protection on both charge and discharge paths
- Independent gate drive outputs for charge and discharge MOSFETs
- Passive cell balancing to equalize cell voltages
- Temperature sensing (external NTC or die temperature input)
- Pack current sensing and fault/interrupt signaling
- Low quiescent current with fault latch/lockout behavior
- Suitable for compact packaging (QFN) with Tape & Reel option (IRTZ‑T)
Note: exact cell count, thresholds, and interfaces are specified in the datasheet; consult it for sourcing and implementation details.

Package

ISL94203IRTZ-T comes in an 8-pin TSSOP (SOP-8) package, RoHS compliant, Tape‑and‑Reel.

Pinout

- Pin count: 16 pins (SOIC/TSSOP-16 package).
- Function: Dual-phase PWM controller for a multiphase buck VRM; provides gate-drive signals for two N-channel MOSFETs and regulation for CPU/core voltage with features like current sensing/limit, soft-start, enable/UVLO, and reference voltages.

Manufacturer

- Manufacturer: Renesas Electronics (Intersil). Intersil is the brand name former for the company, which Renesas acquired in 2017.
- What kind of company: A semiconductor company that designs and manufactures analog, power-management, and mixed-signal integrated circuits for automotive, industrial, and consumer applications.

Application

ISL94203IRTZ-T is a Li-ion/Li-polymer battery monitor and protection IC for 1–4 cell packs. Typical applications: battery management systems in consumer electronics, cordless tools, power banks, RC/hobby devices, portable energy storage, and small EVs. It provides cell voltage monitoring, over/under-voltage protection, overcurrent/short-circuit protection, temperature sensing, and an I2C/control interface to a host MCU for safe, efficient pack operation.
