PMIC - Gate Drivers, containing both high and low side drivers, provide signals to control the switching of power devices like MOSFETs or IGBTs. The HIP2104FRAANZ-T is a high-side driver that allows the output devices to be switched on and off quickly with minimal power loss. This power device is well suited for automotive, industrial, and consumer applications.

The HIP2104FRAANZ-T offers a wide range of features for efficient power control and improved system reliability. The device has a typical 20nm gate charge, a 500V maximum working voltage, and a peak current up to 1.25A. It is also configured with an integrated dead-time generator that reduces the output dead time by up to 3ns, allowing for increased switching frequency and improved efficiency for the overall system.

The HIP2104FRAANZ-T is also equipped with a built-in low-side detection circuit that prevents the unwanted turn-on of low-side MOSFETs. This keeps power devices from unexpectedly running, ensuring that the system remains safe and reliable. Additionally, the device supports unmatched/matched current-sharing, as well as active and passive carrier-based PWM dimming technologies.

The working principle of the HIP2104FRAANZ-T is fairly simple. This high-side gate driver operates in either a bootstrap or low-side gate driver mode. When the device is operating in the bootstrap mode, an external capacitor charges the gate voltage of the high-side device. Then, a control signal from the processor is given to the HIP2104FRAANZ-T and it turns on the high-side device. When the device is switched to low-side gate driver mode, an external capacitor is not needed, as the former charges the gate voltage of the high-side device.

The HIP2104FRAANZ-T is ideal for a variety of applications such as DC-DC converters, power factor correction (PFC) circuits, resonant converters, phase-shift full-bridge converters, and active clamped flyback converters. This high-side gate driver is especially well suited for automotive applications, as it offers overvoltage protection and short-circuit protection to enhance system reliability. It’s also designed with a low-side undervoltage lockout (UVLO) system to prevent low-side MOSFETs from turning on when the voltage is too low.

In conclusion, the HIP2104FRAANZ-T high-side driver is an ideal solution for a variety of power control applications. It’s equipped with a range of features that enable quick, efficient switching with minimal power loss, as well as increased safety and reliability. Additionally, it supports unmatched/matched current-sharing, as well as active and passive carrier-based PWM dimming technologies.
