A power management integrated circuit (PMIC) is a chip that is part of a device’s digital electricity supply system. It is the circuitry responsible for controlling the flow of electricity from a power source to digital components or systems. It serves to protect devices from currents that are too high or too low, optimizing power delivery. A gate driver, which is an integral part of any PMIC, is an integrated circuit used to increase the current supplied to the gate of a field-effect transistor (FET) to ensure it effectively switches from an off to an on state. The ISL6613BEIBZ-T gate driver is an example of a high-performance and high-efficiency PMIC gate driver.

The ISL6613BEIBZ-T is designed to drive the gate of a high side and low side FET, either a single MOSFET or two MOSFETs in series, operating in a synchronous buck, boost, or bidirectional configuration. It is a protected high-side gate driver with embedded charge pump, perfect for a wide range of highly-efficient, high-power-density designs with minimal external components. Key features include: low input voltage of 2.5V to 5.5V, adjustable output voltage from 4.20V to 6V, robust protection that includes cycle-by-cycle current limiting, over-temperature protection, undervoltage lockout, and the ability to withstand negative transient voltage without false triggering.

The ISL6613BEIBZ-T also includes an embedded charge pump that takes two capacitor charges and provides a bootstrap voltage to the high side gate, eliminating the need for an external capacitor. It features sink/source current up to 2A, improved efficiency for both high side and low side switching, improved EMI immunity, and fast switching over the current limiting threshold. In addition, the device contains an adjustable soft-start function that allows the user to adjust the amount of current in the output stage, allowing it to match the user’s application.

The working principle of the ISL6613BEIBZ-T is relatively straightforward. When the high-side switch is off, the supply voltage is zero volts, so there is no gate drive. When the supply voltage is high, the gate drive charge pump counter charges the logic high voltage, providing gate drive voltage to the high-side switch. To turn the low-side switch on, the gate drive charge pump counter charges the low-side switch gates voltage, providing gate drive voltage to the low-side switch.

The ISL6613BEIBZ-T is a popular choice for digital power supply systems in a variety of fields, including medical, automotive, telecom, data center, aerospace, consumer electronics, and more. It is well suited for a variety of applications such as charging systems, hot swap protection, resonant converter topologies, battery cell protection, and wide input voltage range PoE systems.

In conclusion, the ISL6613BEIBZ-T is a powerful PMIC gate driver ideal for a wide array of applications. Its adjustable output voltage, low input voltage, and robust protections make it an excellent choice for those looking for an efficient, high-power-density solution. By combining the ISL6613BEIBZ-T with other components in a digital power supply system, users can attain highly reliable and efficient performance in their desired application field.
