Battery Protection
One-cell Li-ion Battery Protection IC with High-accuracy Overcurrent Detection Designed for Smartphone and Hearing Aid
Nisshinbo Micro Devices Inc. has introduced the new R5619 Series of one-cell Li-ion / polymer battery protection IC that provides overcharge, overdischarge, and charge/discharge overcurrent detections and is suitable for Smart Phone, Tablet PC, and Hearing aids.
TP5100 vs TP4056 Lithium Battery Charging and Protection Module
TP5100 and TP4056 both devices are used for lithium battery charging and protection, though in general consensus they work the same but have many differences.
DW01A Battery Protection IC
The DW01A is a battery protection IC, that provides protection against overcurrent, overcharge, and over-discharge and comes in a small SOT-23-6 package. It also has a very low quiescent current to prevent unnecessary battery drain.
R5449 Series: 1-Cell Li-ion Battery Protection IC with Built-in Driver for High-side Nch FETs and Temperature Protection
RICOH has announced a one-cell Li-ion / polymer battery protection IC R5449 series which can drive external high-side Nch MOSFETs and provides a high-accuracy detection at overcharge and overcurrent, and a high-accuracy charge inhibition for 0V battery.
