The RT9715DGQW is a Multi-channel Steering Switch with Logic-level Power Distribution Switch and Load Driver. It is a type of power management integrated circuit (PMIC) typically used in mobile and IoT applications. This device is specially designed to provide power control and load driver to a variety of mobile applications such as mobile phones, tablet computers, and other portable electronic devices.
Overview:
The RT9715DGQW combines a logic level power distribution switch, load driver, and a multi-channel steering switch into a single chip. The device is highly integrated with a maximum operating voltage of 8V and a minimum operating voltage of 1.8V. The device\'s higher performance ensures that power can be reliably and securely transferred between sources and loads. RT9715DGQW integrates two independent power distribution switches, each with an enable input, output current limit pins, and output enable pins for control of ON/OFF and maximum current. Internally, the two power switches are connected by a multi-channel steering switch which provides multiple levels of isolation and low resistance. Besides, overclocking protection, overcurrent protection, and short-circuit protection are provided. This device also integrates two independent load drivers with adjustable peak currents, a logic-level enable input, and integrated slew rate control circuitry. The load drivers can drive high-side as well as low-side MOSFETS. The output current can be adjusted with an external resistor, allowing maximum external flexibility.Features:
Some of the key features of the RT9715DGQW include:- Operating voltage range DC1.8V to 8V with 8-bit resolution
- Maximum output current of 4A
- -0.3V to 8V voltage range with single rail operation
- Up to three load drivers with adjustable peak current
- Up to four power distribution switches with current limit pins and output enable pins
- Overclocking protection
- Overcurrent protection
- Short Circuit protection
Working Principle:
RT9715DGQW operates on a principle of controlling power distribution with a logic-level Enable signal. The device consists of two independent power distribution switches and two independent load drivers. Each of the power distribution switches accepts a logic-level Enable signal to latch ON or OFF its output. The output voltage is limited to the voltage range between 0.3V and 8V with an adjustable output current limit. The output current is also adjustable with an Internal current limit pins.The two independent load drivers accept logic-level Enable signals to control the power to the load MOSFETs. The internals of the RT9715DGQW integrate a multi-channel steering switch connected between the outputs of the two power switches which allow the load drivers to drive both high-side and the low-side MOSFETS. The output current of the load drivers can be adjusted with an external resistor.Advantages:
The RT9715DGQW offers many advantages as compared to other solutions. Some of the key advantages include:- Highly integrated with a maximum operating voltage of 8V and a minimum operating voltage of 1.8V.
- Power can be reliably and securely transferred between the power sources and loads without dropping voltage.
- Power distribution switches can be shut down with a logic-level Enable signal for power saving.
- Load drivers can be enabled or disabled using the logic-level Enable signal.
- Eliminates the need of multiple discrete components and reduces board area requirements.
- Compact and lightweight: Suitable for mobile and IoT applications.
Application field:
The RT9715DGQW is suitable for a variety of mobile applications such as mobile phones, tablet computers, and other portable electronic devices. It can also be used in applications such as automotive, industrial, and automation systems for controlling and regulating power consumption.The device is specially designed to provide power management and distributed power control for mobile devices with low power consumption. Furthermore, it is suitable for applications where the supply voltage is limited, such as IoT and wearable devices, where the importance of power saving is significant. In conclusion, the RT9715DGQW is an efficient and cost-effective solution for power management in mobile and IoT applications. With its high level of integration and multiple levels of protection, it offers superior performance and reliability.The specific data is subject to PDF, and the above content is for reference
