The SG6105ADZ is an integrated pulse width modulation (PWM) controller with linear current mode architecture that is widely used in battery charging applications and other power supply controllers. As a member of the SG6105 family, the SG6105ADZ is the most advanced, highly integrated device and provides the highest level of protection. As a power supply controller, the SG6105ADZ is designed to provide a regulated output voltage with tight regulation and low ripple noise. Additionally, it is also used in monitoring applications to detect over-current, over-voltage and over-temperature.

The main features of SG6105ADZ include a wide 4V to 60V input voltage range, high accuracy voltage regulation and programmable switching frequency from 250 kHz to 1 MHz. It also features a high performance current mode controller and a fully integrated high power FET output driver for MOSFET, IGBT and other power devices. Furthermore, it also provides built-in under-voltage, over-voltage and over-current protections.

The working principle of SG6105ADZ involves the use of an internal PWM generator in conjunction with a high precision current sense amplifier. At the beginning of each switching cycle, the internal current sense amplifier checks to see if the sensed current rises above the predetermined threshold. If the sensed current is greater than the set threshold, the internal PWM generator will be triggered to reduce the output voltage. The output voltage is regulated by repeating the above process.

The SG6105ADZ is typically used as a motor control driver, switchmode power supply and charger controller. It is also commonly used in battery charging applications such as lead-acid, NiMH and Li-ion. As a motor control driver, it can be used to control the speed and direction of the motor. Furthermore, its built-in protection feature ensures safety and reliability. As a switch mode power supply, the SG6105ADZ can be used to regulate the output voltage with low ripple noise.

The SG6105ADZ is a highly integrated device that provides a robust solution for power supply controllers, monitors, and motor drives. It is designed to provide reliable and efficient operation in even the most demanding applications. With its wide input voltage range, high accuracy voltage regulation, programmable switching frequency, and built-in protections, the SG6105ADZ is an ideal choice for any application requiring power management.
