HIP2101EIB

Gate drivers are essential components of power management integrated circuits (PMICs) as they provide the primary path for the flow of current to the load. The HIP2101EIB PMIC Gate Driver is a robust, highly-integrated driver designed to provide maximum performance in switching, driving and blending applications. In this article, we will discuss the application field and working principle of the HIP2101EIB Gate Driver.

Application field

The HIP2101EIB PMIC Gate Driver is a suitable choice for many types of power management applications. It is an excellent choice for motor driver applications, supplying charge pump and gate drive currents for motors from small to mid-sized sizes. It is also suitable for motion control applications such as digital controllers, steppers, servos and velocity controls. Additionally, it can be used in switch mode power supplies, Smart Grid drive controls and in advanced electronic ballast control systems.

In switching applications, the HIP2101EIB PMIC Gate Driver is able to supply various combinations of primary, secondary and tertiary switch gate drives to enable high efficiency operation. This includes fast turn-on and turn-off speeds, wide linear working range and low electrical noise. Additionally, the device is suitable for driving IGBTs, MOSFETs, MOSFETs with an integrated diode and hybrid IGBTs.

In blending applications, the HIP2101EIB PMIC Gate Driver is able to deliver blending with minimal switching losses and EMI. This is achieved by its unique dielectric mixture and its symmetric output design. Furthermore, it is capable of providing positive and negative peak current stabilization via its integrated charge pump. The device also has temperature resistant features to protect the power switches.

Working Principle

The working principle of the HIP2101EIB PMIC Gate Driver is based on a two-stage process: the first stage is the voltage supply, which charges the integrated charge pump of the device; the second stage is the current delivery, which drives the load. The voltage supply stage is designed to provide the energy to charge the charge pump, which is then delivered to the load through its output stages. The output stages are responsible for delivering the current to the load. The charge pump’s current capacity is dependent on the voltage applied to the device and its dielectric capacity.

The charge pump’s current capacity can be increased or decreased by adjusting the voltage applied to the device. This is done through the input stages of the Gate Driver, which include a control register and an overvoltage/undervoltage protection circuit. The control register provides the user with the ability to adjust the parameters of the charge pump, including the peak current, the switching frequency, the gate drive and the slew rate.

The Gate Driver also comprises a variety of integrated protection features, such as overvoltage protection, overcurrent protection, undervoltage protection and shot through protection. These features ensure that the device is able to survive under demanding electrical conditions. Furthermore, the device is designed to offer superior noise suppression characteristics and thermal protection.

In conclusion, the HIP2101EIB PMIC Gate Driver is a robust, highly-integrated driver that is suitable for a variety of power management applications. It is designed to provide maximum performance in switching, driving and blending applications, while offering a range of protection features to ensure the device’s operational longevity.
