Frequently Asked Questions
What protection functions does the UCC3911DPTR-1 provide for lithium-ion batteries?
The UCC3911DPTR-1 provides three key protection functions for 2-cell series Li-ion battery packs: overvoltage protection (prevents overcharging beyond a set cell voltage threshold), undervoltage protection (prevents over-discharging below the minimum safe voltage), and overcurrent protection (limits excessive discharge current that could damage the battery or connected load). These functions are implemented with fixed thresholds, simplifying design without requiring external resistor networks.
How many battery cells can the UCC3911DPTR-1 protect?
The UCC3911DPTR-1 is a 2-channel device designed to individually monitor and protect two series-connected lithium-ion cells. Each channel independently supervises its assigned cell's voltage, allowing the IC to detect and respond to overvoltage or undervoltage conditions on either cell in the series stack. This cell-level monitoring is essential for maintaining balance and safety in multi-cell battery packs.
What package does the UCC3911DPTR-1 use and what do the suffix characters mean?
The UCC3911DPTR-1 is housed in a 16-pin SOP (Small Outline Package) with a 0.635 mm pin pitch (package equivalence code SOP16, .25). In the part number, 'D' indicates the SOIC package, 'PT' refers to tape-and-reel packaging for automated assembly, 'R' denotes reel format, and '-1' is a version or configuration designator. The JESD-609 code e0 indicates this is not a RoHS-compliant (non-lead-free) variant.
What are typical applications for the UCC3911DPTR-1?
The UCC3911DPTR-1 is well-suited for battery management in portable consumer electronics including laptop computers, portable media players, handheld test equipment, and cordless power tools that use 2-cell lithium-ion battery packs. Industrial applications such as handheld barcode scanners, field instruments, and compact UPS backup batteries also benefit from its integrated dual-channel protection in a small form factor package.
Are there alternative battery protection ICs compatible with the UCC3911DPTR-1?
Alternative 2-cell Li-ion battery protection ICs include devices from manufacturers such as Seiko Instruments (S-8232 series), Ricoh (R5421 series), and Renesas. When selecting an alternative, designers should compare the number of protected cells, overvoltage and undervoltage thresholds, overcurrent detection levels, package type, and pin-out compatibility. The fixed threshold nature of the UCC3911DPTR-1 should be verified against the application's required protection levels before substitution.
