Overview
The ISL9238HRTZ-T is a digital, configurable Buck-Boost battery charger IC from Renesas Electronics Corporation. It supports 1 to 4 series Lithium-ion or Lithium Polymer cells with an input voltage range of 3.2 V to 23.4 V and an output voltage range of 2.4 V to 18.304 V. The device features an SMBus interface for configuration and monitoring. It operates within a temperature range of -40°C to +100°C and is housed in a 32-pin TQFN package (4x4 mm).
Feature Summary
- Digital configurability via SMBus interface for flexible system integration.
- Supports Narrow Voltage Direct Charge (NVDC) and Hybrid Power Buck-Boost modes.
- Integrated protection mechanisms including over-current, over-temperature, and over-voltage safeguards.
Applications
- Tablets and Ultrabooks
- Notebooks
- Portable power banks
- USB-C portable devices
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the exact part number ISL9238HRTZ-T to guarantee correct firmware compatibility and electrical specifications.
Selection Notes
Select this component for applications requiring precise digital control over charging profiles. It is suitable for systems needing NVDC operation to maintain system uptime during charging. Consider the SMBus interface requirements for host communication and verify that the 32-pin TQFN footprint fits the PCB layout constraints.
Part Context
This part belongs to the ISL9238 family of battery chargers. It shares functional similarities with models like ISL9238CHRTZ but may differ in packaging or specific revision details. The HRTZ designation typically refers to the lead-free, halogen-free variant in the standard tray or reel format depending on the suffix.
Replacement Considerations
ISL9238CHRTZ is a related model within the same family. Verify pinout and software compatibility before substitution. Other ISL92xx series chargers may offer similar functionality but require detailed datasheet comparison for electrical parameters and interface signals.
