PMIC - Gate Drivers

Power Management IC (PMIC) is a class of integrated devices used to manage and control power flows in electronic systems. Gate Drivers are a type of digital interface used to drive electronic switches like transistors, FETs and IGBTs. This article will look at one particular type of Gate Driver, the IGD616, discussing its application fields and working principle.

Application Field

The IGD616 Gate Driver is an Integrated Mixed Signal (IMS) Gate Driver IC specifically designed to drive power transistors like IGBTs. It is available in two output configurations providing either dual LV (Low Voltage) or LVDS (Low Voltage Differential Signaling) outputs. It is manufactured in both a standard through-hole package and a surface mount variant.

The IGD616 has been designed to meet the demands of ever-tightening footprint and power dissipation requirements in space-critical applications such as motor control, renewable energy, UPS, solar, industrial drives, and air-conditioning systems. By using the proper source and sink currents, the device supports a wide range of devices from 500V to 1200V.

In order to extend its reach, the IGD616 is compliant with international EMC standards such as EN61000-4-2, EN61000-4-3, EN61000-4-4 and EN61000-4-5. It has also been designed in such a way that it can tolerate high levels of surge and spike voltage. This makes it highly suitable for a number of applications that make use of single-phase, three-phase, and PMSM motors.

Features and Benefits

The IGD616 features a wide operating temperature range (-40°C to 100°C) and is available in either a through-hole or surface-mount package. This makes it appropriate for environments where space is at a premium and where robust, reliable solutions are desired. The device also features logic level drivers, integrated desaturating dead-time control, efficient power saving features, and logic-ground start-up to reduce static / dynamic losses.

Other benefits of the IGD616 include the ability to operate from a wide Input supply voltage range (4.5V to 20V), improved capacitor voltage rating for soft switching, and a low standby power of just 5mA. Additionally, it is designed for ease of use with minimal external components and can be used for both IGBT and SiC MOSFET gate drive applications.

Working Principle

The IGD616 employs a patented logic-ground start-up technology to reduce static losses, switching losses and overall power losses at the point of start-up. The logic high-level drive supplies and logic ground-level start-up methods of operation lead to a high feeling of reliability, as well as an improved system life and an increased efficiency of the power switch.

The device is designed to provide a very fast control and driver turn-off capability with a desaturation protection using a programmable dead-time. It also incorporates an adaptive VCC feature, allowing it to operate with either low or high VCC levels. By using a logic low level to control the PWM (pulse-width modulation) signal and by controlling the gate skew, the device can offer an improved and accurate drive-control capability.

Apart from the fast control and driver turn-off capability, the IGD616 also provides a self-fault protection feature. This feature monitors the current through the IGBTs and shuts down the device if the current exceeds a specified limit. The device also features an over-temperature protection that shuts down the device if the part temperature exceeds a certain limit, thus preventing damage.

Conclusion

The IGD616 is a powerful Gate Driver that has many features and benefits to offer. It is designed to drive a wide range of power transistors and to operate over a wide temperature range. Its patented logic-ground start-up technology and adaptive VCC feature greatly improve system performance, while the self-fault protection, desaturation protection and over-temperature protection add an extra layer of safety. The IGD616 is an ideal choice for applications such as motor control, renewable energy, UPS, solar, industrial drives, and air-conditioning systems.
