HIP4086AB

HIP4086AB is a 3-phase gate driver integrated circuit (IC) manufactured by Intersil. It is a PMIC (Power Management IC) from the category of Gate Drivers. This IC is designed to provide the needed protection and control to three-phase permanent magnet synchronous motor (PMSM) applications.

This IC operates with input voltage ranging from 8–75 V, sup-porting multiple low-voltage and high-voltage topologies across the categories of PMSM motors. Due to its low-voltage range, it is also used in applications such as battery-powered systems and systems with variable-frequency drives (VFDs).

The HIP4086AB IC can drive up to three phases in both unipolar and bipolar configurations. It is capable of generating three independent gate signals for high-side and low-side driven N-channel MOSFETs or IGBTs, with separate control for each gate signal. The control signals for the single-channel gates can be generated from a PWM signal, EN pin, or an analog voltage applied to the EN pin.

For each gate signal, the HIP4086AB provides over-voltage and over-current protection. It also includes a startup voltage limiter (SVL) and a shutdown output for two of the three channels, allowing for a fast and safe shutdown of the motor. Additionally, it has a wide temperature operating range of -40 to 150°C.

In terms of working principle, the HIP4086AB uses the VMOS technology to drive high-side and low-side N-channel MOSFETs or IGBTs. It uses a fast-responding current sense amplifier (CSA) to detect any current overloads and then limits the current to prevent damage to the system. The VMOS structure also enables the IC to quickly switch off the FETs when the EN pin is driven low.

Furthermore, the HIP4086AB includes fault-reporting functionality that informs the system whenever a fault is detected during operation. When a fault is detected, the IC sends a signal to the system through the fault output pin. This signal is used by the system to reduce the gate current, allowing for fast and safe shutdown of the motor.

In summary, the HIP4086AB is a multi-channel gate driver IC from the PMIC – Gate Drivers category, used for three-phase PMSM applications. It operates with input voltage ranging from 8–75 V, providing over-current and over-voltage protection, as well as a shutdown output and temperature protection. Additionally, this IC is equipped with fault-reporting functionality and expansive temperature operating range.
