ISL9241HRTZ

ISL9241HRTZ is a high‑level power-management IC from Renesas Intersil designed to handle Li‑ion battery packs in portable and automotive/industrial applications. It provides a compact, integrated solution for battery charging/discharge control and system power path management, combining regulation, protection, and monitoring in one device.
Key features (typical):
- Battery charge/discharge control and load switching for safe power delivery
- Protection against overvoltage, undervoltage, overcurrent, and thermal faults
- Monitoring and diagnostic outputs
- Configurable control/interface (commonly I2C/SMBus) for tuning and status reporting
HRTZ denotes a specific RoHS-compliant packaging variant of the device.
Common uses:
- Battery-powered consumer devices, industrial equipment, and automotive applications requiring safe, efficient battery management
Note: exact specifications (input/output ranges, current limits, efficiency, protection thresholds) vary by variant; consult the ISL9241HRTZ datasheet for precise details.

ISL9241HRTZ (Intersil) is a high‑efficiency multi‑rail PMIC. Key features commonly include:
- Integrated multi‑stage buck regulators with synchronous rectification for high efficiency
- Programmable output rails, sequencing, and voltage scaling via control interface
- I2C/SPI/PMIC control for monitoring, configuration, and fault reporting
- Protection: overcurrent/short‑circuit, overvoltage/undervoltage, and overtemperature
- Fault/status signaling and watchdog capability
- Thermal sensing with automatic protection
- Low quiescent current for battery-powered applications
- Internal LDOs or LDO support for logic rails
- EMI/EMC considerations (soft‑start, spread‑spectrum, noise reduction)
- Suitable packaging (HRTZ) for compact designs
Note: exact rail count, voltage ranges, switching frequency, and peripheral blocks vary by revision. Please consult the latest datasheet for specific electrical specs and pinout.

Pin count: 28 pins (HTQFN-28). Function: Power-management IC; dual synchronous buck regulator with integrated MOSFETs for CPU/SoC rail generation, with programmable outputs (via feedback resistors) and typical PMIC features (enable, fault/PG, etc.).

Manufacturer: Renesas Electronics Corporation (brand originally Intersil).
What kind of company: Renesas is a Japanese semiconductor company that designs and manufactures integrated circuits, especially analog, mixed-signal, and power-management ICs for automotive, industrial, and consumer applications.
