ADP3416JRZ-REEL

PMIC - Gate Drivers

The ADP3416JRZ-REEL is a monolithic gate driver integrated circuit that provides level shifting, current sourcing, and current sinking capabilities for driving MOSFET and IGBT power devices.

The ADP3416JRZ-REEL is designed to control external N-channel MOSFETs, N-channel IGBTs, and N-channel IGBTs using the under-voltage detection (UVD) and the over-current protection (OCP) functions. The device utilizes a high side and low side driver capable of both level shifting and gate driving. The gate drive allows level shifting of the control edges of the output devices, thus enabling easy integration of the ADP3416JRZ-REEL into different applications. The device is capable of remaining in the Linear mode with a high degree of accuracy.

The ADP3416JRZ-REEL also features a high sensitivity UVD, which allows for detection of an input input signal that exceeds a certain level. As soon as the UVD is invoked, an internal power circuit disconnects the output from the input. It also features an over-current protection feature, which monitors the current flowing through one of the output stages and shuts down the device if the current exceeds a preset value.

Application Field

The ADP3416JRZ-REEL is designed to control any type of N-channel power MOSFETs, N-channel IGBTs, and N-channel IGBTs for a variety of applications that require high power density and robustness, such as power supplies, DC-DC converters, and switching load controllers. The device is also suitable for use in high speed switching circuits and high frequency power converters. Its integrated low side driver can work with any load side gate voltage up to 30V, making it attractive for applications that require high switching speeds, such as microprocessors and other systems.

Working Principle

The working principle of the ADP3416JRZ-REEL can be explained as follows. The device consists of two main parts, a high side and a low side driver. The high side driver is designed to enable level shifting of the control edges of the output devices. It utilizes a voltage balanced, full drive level shifting architecture, which allows the device to operate in either a low side or a high side driver configuration and perform both level shifting and gate driving. The low side driver is designed to source and sink current to the output devices, allowing for precise control of the output without the need for an additional external driver.

The device has two power inputs, one high and one low. When the high side power is applied, the high side driver supplies a voltage that is higher than the voltage of the low side power supply. This voltage is applied to the control edge of the MOSFET or IGBT and causes the device to switch. The device will then remain in the Linear mode, thus allowing for precise control of the current through the device.

The device also features an integrated UVD and OCP, which provide protection against voltage or current overload. When the UVD detects an excessive voltage, the internal power circuit shuts down the device, thereby preventing damage to the device or the system. Additionally, the OCP monitors the current flowing through the output stages and shuts down the device if it exceeds a predetermined level, ensuring safe and secure operation.

The ADP3416JRZ-REEL provides an efficient and cost effective solution for controlling N-channel power devices. It offers robust protection against voltage and current overloads and is capable of remaining in the Linear mode with a high degree of accuracy, making it an ideal choice for high power and high frequency applications.
