The IR2111SPBF device is an intelligent high voltage gate driver for half-bridge and full-bridge applications. This device is placed in the categorization of PMIC - Gate Drivers. It includes two p-channel HEXFET power MOSFETs and their respective high-side and low-side gate drive circuits. The IR2111SPBF controls the two power MOSFETs with logic level inputs and PWM signals. It provides low on-resistance to minimize power losses, while also providing high dV/dt immunity with its adaptive adaptive shoot-through protection (ASTP) circuitry.
The application field of the IR2111SPBF is wide. It is used in motion control applications such as electric air compressors and scissor lifts, as well as other applications such as air conditioners and automatic door locks. It is also ideal for power converters in electric cars, solar panel and other photovoltaic systems. Generally, it is suitable for any applications that require superior control of both power MOSFETs in half-bridge and full-bridge topologies.
The working principle of the IR2111SPBF is based on the following core components:
- The logic gate has two inputs and one output, which is used to control the turn-on and turn-off sequence of the two power MOSFETs.
- The PWM signal is generated by a microcontroller and is used to control the speed and torque of the motor.
- The power MOSFETs are connected in a half-bridge or full-bridge configuration for high-power switching.
- The high and low voltage driver circuits provide the necessary gate drive voltages for the power MOSFETs.
- The ASTP circuitry provides active shoot-through protection and overcurrent protection.
When the logic input is low, the logic gate enables the low-side MOSFET while disabling the high-side MOSFET. The low and high voltage drivers then provide the necessary gate drive voltages to turn on the low-side MOSFET. When the logic input is high, the logic gate enables the high-side MOSFET while disabling the low-side MOSFET. The low and high voltage drivers then provide the necessary gate drive voltages to turn on the high-side MOSFET.
In addition, the ASTP circuitry, which consists of a current sensing circuit, an overvoltage protection circuit and an undervoltage protection circuit, protects against shoot-through and overcurrent conditions. The ASTP circuitry allows for fast reaction to fault conditions, thus preventing catastrophic failures.
The IR2111SPBF provides a flexible, robust, and cost-effective solution for motor control and other applications that require superior control of both power MOSFETs in half-bridge and full-bridge topologies. It has a robust design with multiple safety features, making it suitable for the most demanding applications. It also integrates all necessary components, eliminating the need for external components, thus reducing the overall system cost.
