HIP2100IRZT is an integrated dual gate driver IC (Integrated Circuit) device designed by Renesas Electronics, applicable for applications such as DC/DC converters. Often used in PMIC (Power Management IC) applications, notably gate drivers, the device works by processes, such as a power gain stage, a current limit stage, a level shift stage and a diode drive stage.

The HIP2100IRZT is an integrated dual gate driver IC with a low quiescent current, 1.8A source and 1A sink capability, and a maximum supply voltage of 28V, VDD of 4.5V to 11.5V, making it suitable for a very wide range of applications. The device contains two pairs of high and low side drivers that can be used independently or tied together to form a dual-gate driver.

The power gain stage is an integrated circuit block consisting of an output driver, a dual-channel inverter, and an output isolation circuit. Through this power gain stage, the HIP2100IRZT generates a robust level shift path between the input and output sides of the device. The output of the stage is available as either a high or low side switch, allowing the high and low side legs of the device to be controlled independently.

The current limit stage provides an easy-to-implement current limitation mechanism. When the over-current condition is detected, the HIP2100IRZT will reduce the switching frequency and enable a current limiting mechanism. This helps to protect the device, by limiting the current and preventing damage due to excessive current.

The level shift stage is responsible for shifting the low side output driver’s gate voltage in order to properly match the available gate voltage of the high side output driver’s gate. This allows the device to perform as a full-wave buck-boost driver, making it suitable for buck-boost applications. The HIP2100IRZT also has a diode drive stage, which is responsible for rapidly discharging the high and low side drivers when the high side output voltage drops below the low side output voltage.

In PMIC applications, the HIP2100IRZT is typically used for the power management of DC/DC converters, enabling higher current flows and improved switching efficiencies. Its high output current capability (1.8A source and 1A sink) makes it suitable for use in buck-boost applications, and its current-limiting feature allows it to provide robust protection for the device against over-current conditions. Its integrated dual gate driver IC configuration makes it ideal for creating dual-output drivers, allowing for both high side and low side outputs.

In addition to its applications in PMIC, the HIP2100IRZT can also be used to drive DC motors, providing a full-wave controller with both high and low side outputs. Its integrated inverter allows the device to provide robust commutation and safeguarding against short-circuits, while its current-limiting feature helps protect the device from excessive currents. Additionally, its diode drive stage can be used to increase motor torque and improve motor dynamic performance.

Overall, the HIP2100IRZT is an ideal device for use as a dual gate driver in PMIC applications, as well as for driving DC motors. Its low quiescent current, high output current capability, current limit stage, and integrated inverter make it suitable for a wide range of applications, from DC/DC converters to DC motors. Additionally, its diode drive stage and integrated dual gate driver IC configuration make it ideal for creating dual-output drivers.
