Power management integrated circuits (PMICs) are a type of integrated circuit that manages the power of other circuits by sequencing and controlling the power requirements of multiple components of a system. PMICs are commonly used in many electronics, such as cell phones, personal computers, and other small electronic systems. Gate drivers, which form a key part of PMICs, enable the control of power MOSFETs by providing an interface between logic circuits and the voltage driving MOSFET gates. One such gate driver is the ISL6614BCBZ.

ISL6614BCBZ Application Fields

The ISL6614BCBZ is a high performance, low-side and high-side MOSFET driver. It contains two independent and complementary output drivers, which provide a peak current of 2.5A and a continuous current of 1.0A in either signal direction. It includes an over temperature and over voltage protection, over temperature signal shift and under voltage lockout (UVLO). The ISL6614BCBZ has three logic inputs, an ENABLE input, a RESET input and a CONFIGURATION input, which can be utilized to configure the power MOSFETs in various topologies.

The ISL6614BCBZ is ideal for various applications, including both DC-DC and DC-AC converters, as well as motor control systems, such as brushless DC and switched reluctance motors. It is also suitable for protection circuits in communications systems, renewable energy applications, and industrial automation. Furthermore, this device is ideal for driving synchronous and asynchronous MOSFETs.

ISL6614BCBZ Working Principle

The ISL6614BCBZ gate driver utilizes a triple channel configuration, providing all the current needed to control the gate of MOSFETs. In each channel, two power MOSFETs are connected at the source, while the gate of each power MOSFET is driven independently by an output driver. This gate driver operates in different switching modes, depending on the logic level of the CONFIGURATION and ENABLE inputs. By utilizing the ENABLE input, a system designer can enable and disable the switching of the gate driver. Additionally, the RESET input is used to reset the operating state of the gate driver.

The high performance of the ISL6614BCBZ gate driver is achieved by its on-board charge pump, which generates enough voltage to switch power MOSFETs with higher gate capcitance. The output driver enables high-current MOSFETs to be utilized, thus enabling higher-power performance. It also provides much higher efficiency when compared to other conventional gate drivers.

Furthermore, the ISL6614BCBZ gate driver features thermal protection, making it robust and reliable. This device also offers an adjustable over-voltage protection that can be used to limit the voltage that is applied to the gate of the power MOSFETs. It supports several operating modes, such as pulse width modulation (PWM) and pulse density modulation (PDM) modes. Additionally, this device also offers a programmable dead time setting.

Conclusion

The ISL6614BCBZ gate driver is designed to sequence, control, and supply the power to multiple components of a system. The triple channel configuration of this gate driver enables a higher current peak, while its adjustable over-voltage protection provides an added layer of safety. It is suitable for many applications, such as DC-DC and DC-AC converters, motor control systems, communications systems, and renewable energy applications. By utilizing the ENABLE, RESET, and CONFIGURATION inputs, system designers can configure the power MOSFETs in various topologies. This gate driver provides high performance, robustness, and reliability, making it an ideal choice for many applications.
