概述

Description

ISL9241HRTZ is a compact, high-efficiency battery charger and power‑path management IC from Renesas/Intersil. It provides Li‑ion/Li‑poly charging and system power management in one device, with programmable charging current and voltage, automatic input current limiting, and seamless power path so the system is powered while the battery charges. The IC includes protection features (short-circuit, overcurrent, overvoltage, overtemperature, etc.) and an I2C-compatible interface for configuring parameters and monitoring status. The HRTZ suffix denotes the specific package/variant. Typical applications include portable devices, power banks, and automotive/industrial equipment requiring safe, efficient charging in a small footprint. For exact electrical specs, pinout, and protection thresholds, refer to the ISL9241HRTZ datasheet.

Features

ISL9241HRTZ is a high-integration power-management IC (PMIC) from Intersil/Renesas designed for compact, multi-rail systems. Typical features include:
- Integrated multi-rail DC-DC converters with high efficiency
- Wide input range and flexible voltage outputs
- Programmable output voltages and sequencing
- Digital control and monitoring via I2C/SMBus interface
- Fault protection: UVLO/OVLO, overcurrent/short-circuit protection, thermal shutdown
- Power-on reset and fault/status reporting
- Low quiescent/standby current
- Small package (HRTZ) suitable for space-constrained designs
- Automotive-grade option available (where applicable)
Note: exact specs (voltages, currents, supported rails, protocols) vary by revision. Consult the latest datasheet for precise parameters.

Package

QFN package (leadless) in a 4×4 mm footprint with an exposed thermal pad.

Pinout

- Pin count: 16 pins
- Function: Intersil/ Renesas ISL9241HRTZ is a power-management IC (PMIC) battery-charge controller with a buck regulator and power-path control for Li-Ion applications.

Manufacturer
