Overview
The UC2906Q is a sealed lead-acid battery charger IC manufactured by Texas Instruments. It operates with a supply voltage up to 40 V and supports output voltages of 20 V with an output current capability of 2 A. The device is housed in a 20-PLCC package (9x9 mm) designed for surface-mount installation. It functions within a temperature range of -40 °C to +70 °C. This component is classified under battery management and charge management products, specifically tailored for linear lead-acid charging applications.
Feature Summary
- Designed specifically for charging sealed lead-acid batteries
- Integrates linear charge management functionality
- Supports surface-mount installation via PLCC package
Applications
- Sealed lead-acid battery charging systems
- Battery management units requiring linear regulation
- Industrial power management modules
Procurement Notes
Verify the specific suffix and package variant when sourcing, as the UC2906Q series includes multiple pin configurations such as PDIP and SOIC. Confirm availability status, as some variants may be obsolete or end-of-life. Ensure the selected part matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component for applications requiring dedicated lead-acid battery charging with linear topology. Consider the 20-PLCC package constraints for PCB layout. Evaluate thermal dissipation requirements given the linear regulation method. Verify compatibility with system supply voltages up to 40 V and ensure the operating temperature range meets environmental demands.
Part Context
The UC2906Q belongs to the UC2906/UC3906 family of battery chargers from Texas Instruments. These devices are engineered for lead-acid battery applications, offering integrated control for charging profiles. The Q variant specifically utilizes a 20-pin PLCC package, distinguishing it from other family members that may use DIP or SOIC packages.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Some related models like UC2906N or UC3906N exist but differ in package type (PDIP/SOIC vs PLCC). Verify functional equivalence and pinout compatibility before considering alternatives.
