The working principle of the MP2661GC-XXXX-P device is based on the buck/charge topology, where the output voltage of the device is regulated by internally comparing a reference input to an internal error amplifier. The power MOSFETs are connected in a synchronous rectifier configuration, where the high-side and low-side MOSFETs switch alternately. By adjusting the duty cycle of the PWM signal generated by the internal PWM controller, the regulated output voltage is regulated and maintained within a certain range.

The MP2661GC-XXXX-P\'s internal current-sense resistor is used to detect the output current of each charging channel, allowing the device to accurately regulate the output current of each channel in order to protect the battery from overcharging and damage. Once the battery has been fully charged, the device will switch to trickle-charging mode and continuously monitor the current going in and out of the battery.

The MP2661GC-XXXX-P device is designed to provide Integrated Power Distribution, Flexible Safety, and Efficient charging, in a very compact package. The device offers integrated high-side and low-side power MOSFETs for each charging channel, with programmable current-limit and thermal-limit settings for each channel. Users can also define which battery chemistry will be used for each channel, allowing for multi-chemistry charging support. The device is highly efficient and optimized for low-noise operation, enabling minimal EMI for improved system performance.

In short, the MP2661GC-XXXX-P device from PMIC - Battery Chargers is perfect for applications needing efficient multi-chemistry charging support. With integrated PWM controller, synchronous buck/charge controller and power MOSFETs, the device provides both a regulated output voltage and a current-limited charging profile, while also offering integrated high-side and low-side power MOSFETs and programmable current-limit and thermal-limit settings for each channel.
