The BQ27220 is a high-precision low-power fuel gauge IC manufactured by Texas Instruments. The BQ 27220 device uses the Compensated End-of Discharge Voltage (CEDV) algorithm to monitor the battery parameters.
The L4941 is a 5V low dropout positive voltage regulator. It can regulate the output voltage even when the input voltage is only slightly higher than the output voltage. This is beneficial in battery-operated systems where maximizing battery life is crucial.
The NCP3170 is a synchronous buck regulator with integrated switching elements. It has a wide Input Voltage Range from 4.5V to 18V and it can deliver up to 3A output current. The NCP3170 uses current mode control for fast transient response and easy loop compensation.
The TDA7293 is a powerful class AB audio amplifier IC suitable for high-quality audio systems. The TDA7293 features a DMOS power stage, which offers high efficiency and low distortion. The TDA7293 can deliver up to 100 watts of power with an 8-ohm load.
The LA4440 is a high-performance, dual-channel audio power amplifier IC manufactured by Sanyo. It is a low-cost cost widely used audio amplifier IC. Once was one of the most popular choices for car stereos and portable boomboxes.
The LM3886 is a high-performance audio power amplifier which is capable of delivering 68W of continuous power with 0.1% THD+N (Total Harmonic Distortion + Noise). The peak output power of this IC is about 135 watts.
The TDA2002 is a cheap, 8W class B audio power amplifier that is designed for use in car stereos and portable audio systems. This is a 5-pin compact, reliable, and efficient amplifier IC. We can get up to 15w power by bridging 2 TDA2002 ICs together.
