HIP4081AIBZ

The HIP4081AIBZ is an integrated, high-speed CMOS gate drive circuit housed in an 8-pin, dual-in-line package. It is designed to drive a variety of power switching transistors with the peak-current drive capability of 500mA, in either common-source or source-follower configurations. This product is suitable for a wide range of Power Management IC (PMIC) applications, such as motor and lighting control, battery power management, and power IC and subsystem protection circuit.

The HIP4081AIBZ has two independent outputs, each with a peak current capability of 500mA and a voltage swing capability of 9V. This allows the device to drive power switching transistors of all sizes, including those in the power MOSFET family, in either common-source or source-follower configurations. The outputs can also control relays, lamps, and a variety of other loads. The high-speed CMOS outputs can be operated at frequencies up to 1MHz. The differential inputs are designed to interface directly with standard logic levels, and the voltage ratings can be adjusted to suit the logic levels.

The HIP4081AIBZ PMIC gate driver also has many other features that make it well suited for a variety of applications. It includes a low-power mode, in which it reduces its power consumption to microamperes, and a soft-start function, which allows devices to power up gradually and smoothly. The device also provides a wide range of protection features, including input and output overvoltage protection, overcurrent protection, and shutdown protection.

On the inside, the HIP4081AIBZ PMIC gate driver circuit contains a high-speed CMOS inverter and logic that control the output current and voltage levels. It also contains level-shifting circuitry, which allows signals to be directly converted from TTL or CMOS logic levels to the high-voltage circuits used by the output power switching transistors. Additionally, it also contains thermal protection and current protection circuitry, as well as an output disable feature that prevents the output from inducing excessive current in the source.

In summary, the HIP4081AIBZ is an ideal PMIC gate driver that provides the peak-current drive capability of 500mA and the voltage swing capability of 9V. It is suitable for a wide range of PMIC applications and features low-power, soft-start, and protection features. Its high-speed CMOS output can be operated at frequencies up to 1MHz, and it contains level-shifting circuitry as well as an output disable feature.
