The MAX17043 is a tiny, cheap host-side fuel gauge IC specifically designed for single-cell lithium-ion batteries. Unlike the traditional way, this IC uses a modelling scheme called model gauge to monitor the state of charge (SOC) of the battery.
The MIC5205 is an ultra-small, highly efficient linear voltage regulator available in both adjustable and fixed output voltage variants. This small IC offers ultra-low-noise output, very low dropout voltage and very low ground current.
This BQ29700 is a single-cell Li-ion/Li-polymer battery protection IC from Texas Instruments. BQ29700 features all the standard protection features such as Overcharge, Over-discharge, Charge overcurrent, Discharge overcurrent, and Load short-circuit protections.
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.
Littelfuse has today announced the extension of its ITV9550 surface-mountable Li-ion battery protector series. These fuses safeguard battery packs against overcurrent and overcharging (overvoltage) conditions.
The NB7141 is a 1-cell Li-ion / polymer battery protection IC which provides overcharge, overdischarge, charge / discharge overcurrent and short circuit protection, with built-in watchdog timer.
