MC33340DR2G

Battery Chargers Overview

The MC33340DR2G is a battery fast charge controller manufactured by onsemi, designed for NiCd and NiMH chemistries. It operates within a maximum supply voltage of 18V and features a switching frequency of 760kHz. The device supports an output current capability of 50mA and functions across a temperature range from -40°C to +85°C. Packaged in an 8-pin SOIC with a 1.27mm pitch, it integrates control logic for efficient charging profiles.

Battery Chargers Feature Summary

• Supports fast charging protocols for Nickel-Cadmium and Nickel-Metal Hydride battery types
• Integrates high-frequency switching control at 760kHz for compact external component design
• Provides robust protection mechanisms inherent to dedicated battery management controllers

Battery Chargers Applications

• Portable electronic devices requiring NiCd or NiMH battery charging
• Consumer electronics with limited space for power management components
• Industrial equipment utilizing rechargeable nickel-based battery packs

Battery Chargers Procurement Notes

Verify the specific suffix 'DR2G' corresponds to the tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure input voltage does not exceed the 18V absolute maximum rating to prevent device damage during procurement validation.

Battery Chargers Selection Notes

Select this component when designing systems specifically for NiCd or NiMH batteries rather than Lithium-ion chemistries. The 760kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 8-pin SOIC package constraints for PCB layout and thermal dissipation requirements relative to the 50mA output capability.

Battery Chargers Part Context

This part belongs to the MC33340 series of battery charge controllers. It serves as a specialized solution for non-lithium battery technologies, distinguishing itself from general-purpose linear chargers by offering integrated switching regulation. The DR2G designation indicates a specific surface-mount variant optimized for automated assembly processes.

Battery Chargers Replacement Considerations

The MC33342D is identified as a comparable industry-standard alternative within the same product family. Verify pinout compatibility and specific charging algorithm differences before substitution. Ensure the replacement meets the same voltage and current specifications required by the original design.
