Introduction
IR2184S is a power management integrated circuit (PMIC) manufactured by International Rectifier (IR). It is under the category of gate drivers and is used to enable on-chip control and protection of power MOSFETs. This PMIC is primarily used by power engineers, who are tasked with designing power electronic systems that must meet tight performance and cost targets.
Application Fields
The IR2184S is an essential component for wide range of power applications. It is used when high performance or high voltage are required for DC-DC converters, power factor correction, adaptive load systems, active power filters, solar inverters and motor control drives. The device may also be used as a standard level shifter or as a bidirectional gate driver.
The device is designed to support high current (up to 20A) gate drive requirements of power MOSFETs and IGBTs. Its features such as the internal level shifting technology, adjustable under-voltage lockout and adjustable dead-time, provides the convenience of one-stop gate drive solution for gate drive circuits.
Working Principle
The IR2184S is based on the traditional current source topology and has two inputs (IN1 and IN2). The selected input is applied to the two gates of the two power semiconductor switches connected to H bridge mode. The upper switch is connected to Vcc, while the lower one is connected to ground. As long as the voltage on either IN1 or IN2 is above the set under-voltage lockout (UVLO) threshold, the required gate drive current is limited by the internal current generation circuit.
The IR2184S also includes a dead-time generator circuit. The dead-time circuit operates by controlling the opposite gate by carefully adjusting the turn-on and turn-off timing. The dead-time period is configurable by setting two external resistors. This allows the power device (internal FET) being driven to be off during that period, thus preventing any short circuit current. The device also contains integrated feedback circuits, thermal shutdown and short-circuit protection.
Conclusion
The IR2184S is a power management integrated circuit (PMIC) that is classified as a gate driver. It is primarily used for power applications such as DC-DC converters, power factor correction, adaptive load systems, active power filters, solar inverters and motor control drives. The device is designed to support high current gate drive requirements of power MOSFETs and IGBTs. It features internal level shifting technology, adjustable under-voltage lockout, adjustable dead-time and integrated feedback circuits, thermal shutdown and short-circuit protection.
