Overview
The ISL9519IRTZ is a highly integrated narrow VDC system voltage regulator and battery charger controller manufactured by Renesas Electronics. It operates with an adapter voltage range of +4.5V to +22V and supports over 8A battery charger current and over 8A adapter current. The device features ±0.5% system voltage accuracy from -10°C to +100°C and ±3% accurate input and battery charge current limits within the same temperature range. It includes an SMBus 2-Wire Serial Interface for programmable operating parameters, variable switching frequency at light loads, and fixed frequency operation at higher loads.
Feature Summary
- Integrates system voltage regulation and battery charging control in a single highly integrated controller.
- Supports trickle charging for deeply discharged batteries while maintaining a user-defined minimum system voltage.
- Features automatic adapter in-rush FET control and isolation FET control for enhanced power management.
- Includes built-in protection mechanisms such as battery short circuit protection and fast system-load transient response.
Applications
- Narrow Voltage DC (NVDC) systems
- Hybrid Power Battery Charger applications
- Systems powered by battery packs or regulator/charger outputs
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and package integrity upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing designs. Validate thermal performance under actual load conditions before final implementation.
Selection Notes
Select this component for applications requiring precise system voltage regulation alongside battery charging capabilities. Ensure the design accommodates the +4.5V to +22V adapter input range. Verify that the required current settings align with the 6-bit configuration options available via the SMBus interface.
Part Context
The ISL9519 belongs to the ISL9519 series of power management ICs designed for portable computing and industrial applications. It serves as a specialized solution for managing power distribution between AC adapters and battery packs in systems where system voltage must not exceed maximum battery voltage levels.
Replacement Considerations
The ISL95522A is identified as a direct replacement product offering similar functionality with SMBus interface support for hybrid power battery charging applications.
