Overview
The NCP1835MN24R2G is a single-cell lithium-ion battery charger manufactured by onsemi. It provides a maximum output current of 1 A and regulates the charging voltage to 4.2 V. The device operates within a supply voltage range of 2.8 V to 6.5 V. It is housed in a DFN-10 surface-mount package suitable for SMD/SMT installation. The component functions within an operating temperature range from -20 C to +70 C.
Feature Summary
- Designed specifically for single-cell lithium-ion battery management applications
- Integrates charge management circuitry for regulated constant-current and constant-voltage charging profiles
Applications
- Single-cell lithium-ion battery charging systems
- Portable electronic devices requiring compact power management solutions
- Battery-powered consumer electronics
Procurement Notes
Verify the exact part number suffix, as the provided model lacks the 'G' designation found in official documentation. Confirm availability status, as records indicate this specific variant may be discontinued or out of stock. Ensure compatibility with the DFN-10 footprint and verify thermal requirements against the specified operating temperature limits before procurement.
Selection Notes
Select this component when designing circuits for single-cell lithium-ion batteries requiring a 1 A charge current and 4.2 V regulation. Consider the DFN-10 package constraints and the 2.8 V to 6.5 V input voltage range. Evaluate the -20 C to +70 C operating temperature range against environmental conditions. Verify that the single-output configuration meets system power needs without requiring additional parallel channels.
Part Context
This component belongs to the onsemi battery management product line, categorized under PMIC - Power Management ICs. It is distinct from other onsemi series such as the NCP5183 gate drivers or NCP3335 LDO regulators. The NCP1835 series focuses exclusively on linear charging solutions for portable applications, differentiating itself from switching regulators like the NCP323X buck converters.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer documentation for potential cross-references or updated revisions.
