Product Overview: UCC3952PW-3 by Texas Instruments

The UCC3952PW-3, manufactured by Texas Instruments, is a highly integrated and advanced battery protection device designed for lithium-ion and lithium-polymer batteries. This precision circuit is engineered to ensure the safe operation of rechargeable battery packs by providing essential protective functions against overcharge, overdischarge, and overcurrent conditions.

Key Features

• Overcharge Protection: The UCC3952PW-3 offers reliable overcharge protection by monitoring the voltage of each cell in a battery pack. If the voltage of any cell exceeds the predefined threshold, the device will activate its internal control circuitry to prevent further charging, thereby safeguarding the battery cells from potential damage.
• Overdischarge Protection: To prevent battery damage due to deep discharge, this device continuously monitors the cell voltages and will disconnect the load when the voltage drops below the minimum allowable level, ensuring the longevity and health of the battery pack.
• Overcurrent and Short Circuit Protection: The UCC3952PW-3 is equipped with overcurrent detection that reacts swiftly to excessive current draw, as well as short circuit conditions. It provides immediate response to protect the battery pack from hazardous operating conditions.
• High-Accuracy Voltage Sensing: With precise voltage sensing capabilities, the UCC3952PW-3 ensures that protective measures are taken at the correct voltage thresholds, maintaining the balance and performance of the battery pack.
• Low Power Consumption: Designed for efficiency, the device features low quiescent current, minimizing the power drawn from the battery when in standby mode, thus preserving battery charge during periods of inactivity.

Applications

The UCC3952PW-3 is versatile and can be used in a variety of applications where battery safety and longevity are of utmost importance. It is ideal for use in portable consumer electronics, such as smartphones, tablets, and laptops, as well as in medical devices, power tools, and electric vehicles that require reliable battery management.

Package and Quality

This device is available in a TSSOP (Thin Shrink Small Outline Package) format, which is suitable for surface mount technology (SMT) and offers a compact footprint for space-constrained applications. Texas Instruments ensures the highest quality and reliability of its products, and the UCC3952PW-3 is no exception, meeting stringent industry standards for performance and durability.
