The UCC3957M-4 from Texas Instruments is a BiCMOS battery pack protector IC specifically designed for three- or four-cell lithium-ion battery configurations. It operates with external P-channel MOSFETs to provide robust protection against overcharge, overdischarge, and excessive discharge currents.
Key features include a typical supply current consumption of 30 µA, which drops to a mere 3.5 µA in sleep mode, making it suitable for low-power applications. The device boasts a wide VDD supply range of 6.5 V to 20 V and incorporates a highly accurate internal voltage reference. It also features externally adjustable delays for its overcurrent controller and detection for loss-of-cell sense connections.
This IC is housed in a 16-SSOP package and is designed for surface mount applications. Its fault protection capabilities include overcurrent, overvoltage, and undervoltage conditions, ensuring the safety and longevity of the battery pack. The UCC3957M-4 is ideal for integration into portable electronics, power tools, and other battery-powered devices requiring reliable lithium-ion battery management.
The operating temperature range for this component is -20°C to 70°C (TA). The package is a 16-SSOP with a width of 0.154 inches (3.90mm).
