HIP2100IR4Z is a highly integrated, high-voltage, three-phase power management integrated circuit (PMIC) designed for battery operated, multicore microprocessor systems. It features a multi-phase low-side gate drivers with integrated capacitive sense for switching power electronic loads. The HIP2100IR4Z offers an optimized setup time for high-speed, dynamic operation and is ideal for automotive and handheld applications.

HIP2100IR4Z application field mainly includes a wide range of power electronic applications such as DC-DC converters for microprocessors, memory and I/O voltage conversions, battery cell management, LED lighting, and uninterruptable power supplies (UPS). Its highly integrated nature means that it can easily be integrated into a variety of system designs.

The HIP2100IR4Z is designed to drive up to 3 low-side MOSFETs, allowing for high current motor drives and high-frequency operation. The power source can be an unregulated DC input or a 3-phase supply allowing for maximum system efficiency and fault tolerance. The integrated capacitive sensing capabilities enable the IC to adjust its drive signals to account for changes in output load.

The HIP2100IR4Z has an adjustable low-side gate drive voltage range of 5.0V to 60.0V and adjustable high-side gate drive voltage range of 1.8V to 5.5V, ideal for modern high-performance applications. This device also features internal thermal shutdown and output fault protection to ensure proper operation in harsh environment conditions. Furthermore, the HIP2100IR4Z utilizes an on-chip clock signal generator which enables it to dynamically adjust the drive signals consistent with its operating frequency.

The working principle of the HIP2100IR4Z is simple: it is designed to drive power MOSFETs in pulse-width modulation (PWM) mode for high current motor applications and in voltage-mode for switch-mode power supplies. The driver outputs are comparator based and the switching frequency is adjustable through the clock signal generator. The IC also has the ability to sense the capacitance at the output of the MOSFETs and adjust the drive signals accordingly in order to maximize efficiency and protect the load from damage due to an overloaded transformer or faulty power supply.

The HIP2100IR4Z is an ideal solution for highly efficient DC-DC conversion and motor drive systems as it offers adjustable switching frequencies and a programmable gate drive voltage levels as well as comprehensive fault protection. This versatile PMIC is therefore suitable for a wide range of applications and is highly suitable for automotive, hand-held and medical device applications.
