The BD3893FV-E2, manufactured by ROHM Semiconductor, is a system power switch that integrates integrated power MOSFETs, high-side and low-side N-channel FET drivers in a single chip. It is designed to increase power saving and reduce the component count in power supplier system, cellular phones, battery-powered products, and automotive applications.
The power switch is optimized to drive MOSFETs in order to maximize efficiency and reduce power consumption when controlling power switching. The BD3893FV-E2 includes an integrated MOSFET driver, a high-side and a low-side control switch, and an advanced current-limit control circuit as well as a variety of features for more efficient control of power switching and power management. The device is used to control the battery power management and provide power supply.
The typical application field for the BD3893FV-E2 is any device that requires two-stage power switching, including cell phones, laptops, game consoles, battery-powered products, and automotive applications. The device is highly reliable and can be used in automotive applications like electronic power steering, air conditioner, other body and chassis application in passenger car, light-duty vehicle, and heavy-duty vehicle.
The working principle of the BD3893FV-E2 is relatively simple. It is designed to minimize current consumption in power switching applications by executing its operations in two stages. In the first stage, the high-side MOSFET is driven with a low-side power switch. This low-side power switch is controlled by an integrated MOSFET driver. In the second stage, the low-side MOSFET is driven with a high-side power switch, controlled by the same integrated MOSFET driver.
In order to protect the device from damages that may result from short-circuit or overload conditions, the BD3893FV-E2 utilizes a current limit control circuit. This current limit control circuit monitors the gate drive current of the high-side MOSFET. If the monitored gate current exceeds the preset level, the integrated driver will automatically shut off the power switch and prevent further damages from occurring. Additionally, the device includes a sleep-mode function, which can help conserve power by switching off the power switches when the device is not in use.
The BD3893FV-E2 is designed to provide efficient control of power switching and power management, making it an ideal choice for applications that require two-stage control. Its low current consumption and current-limiting protection make the device suitable for high-density applications found in automotive and portable electronic systems.
