The HIP4086APZ is a family of 900V high voltage P-channel MOSFET drivers. They are designed and optimized specifically for efficient driving of high side power MOSFETs. These drivers feature logic-level to 900V gate-drive capability over a wide operating range. These drivers are available as both 8-pin DIPs and SO packages.

The HIP4086APZ drivers are designed for universal high-side gate drivers for MOSFETs, IGBTs, and bipolar transistors. The drivers are optimized for driving power MOSFETs and IGBTs in multi-phase or phase-shifted high current buck converters, synchronous rectifiers, and full-bridge circuits. They are also designed to provide high-speed logic-level gate drive solutions for both low- and high-side switching applications. With its wide supply voltage range and high-speed performance, the HIP4086APZ provides a cost-effective way of driving large SOI power devices.

The HIP4086APZ is available with four different logic input thresholds. The threshold voltage is highlighted in the device\'s part number, allowing the user to select the appropriate device for the chosen logic family. It offers the designer a way of selecting the right device for each application.

The HIP4086APZ is a family of single-package open-drain gate drivers that include an output buffer, a dead-time insertion circuit for damage preventions, and a voltage clamping feature. The output buffer is designed to protect the gate driver from voltage transients, and also provides fast switching of the output. The dead-time insertion circuit prevents simultaneous conduction of both high-side and low-side devices, reducing parasitic ringing and heat generated from the power MOSFETs.

The primary features of the HIP4086APZ are: high voltage (up to 900 V) capability, wide supply voltage range (4.5-36 V), low on-resistance, low quiescent current, fast switching, high speed buffer, and low-side gate-drive capability. Its wide supply voltage range and high switching speed make it an ideal choice for high efficiency multi-phase and phase-shifting DC-DC converters. It also has a reverse voltage clamping feature to protect the output circuit from negative-going transients.

In addition, the HIP4086APZ also offers an internal enable-disable feature for power-up/power-down sequences. This ensures that the driver is disabled during power-up and power-down cycles, allowing the designer to easily implement safe power-up/power-down designs with minimal component count.

In terms of working principle, the HIP4086APZ uses a source driver to switch the output MOSFET. When the logic input level is low, the output MOSFET is switched off, while when the logic level is high, the output MOSFET is turned on. This allows the output to be switched on and off quickly, enabling efficient power switching applications. The high side gate driver also includes an enable line which can be used to enable or disable the gate driver. This feature helps in implementing safe power-up and power-down sequences for power switching applications.

The HIP4086APZ driver is an ideal choice for high current buck & boost converters, synchronous rectifiers, PWM inverters, full-bridge circuits, and other high-voltage, high-frequency switching circuits. Furthermore, its high switching speed, low-side gate-drive, and low-quiescent current make it an ideal choice for high-efficiency DC-DC switches and linear power supplies. With its wide operating range and high-speed performance, HIP4086APZ is the preferred choice for driving large SOI power devices.
