IR2136STR Application Field and Working Principle

PMIC - Gate Drivers are commonly used in power switching applications requiring high capacity switch and control. The IR2136STR is a specialty gate driver with features designed for this application. It is a one-package two-channel full bridge gate driver, designed to drive bipolar and unipolar stepper motors, solenoids, and valves.

Overview

The IR2136STR is a complete, high-performance motor driver engineered to provide flexibility, robustness, and control in a single 5mmx7mm package. It is one of a family of high-power MOSFET gate drivers providing the highest grade performance and reliability.The IR2136STR is a complete 2-channel, full bridge gate driver. It utilizes a non-inverting, CMOS-output high- and low-side driver, clocked at up to 25MHz. The IR2136STR is capable of driving up to 40V, 150mΩ MOSFETs at a 2kV ESD rating. Its high-side and low-side gate drivers feature short-circuit protection, providing the high level of robustness and reliability expected from high-power MOSFETs.

Functionality

The IR2136STR eliminates the complexity of driving motor brushed and brushless DC motor, stepper motors, solenoids, and valves, allowing them to be easily integrated into any end product application through on-chip control modes and fault protection circuits. It also allows systems to make short switching times with fast rise/fall times, enabling more efficient operation and longer motor lifetime.The IR2136STR supports an integrated start up, speed control, and fault protection circuits. The start-up circuit provides a simple way to perform pull-in operation and to keep the motors in step without additional complexity or external components. The speed control circuit uses a PWM generator to provide control over the motor speed. The fault protection circuit in the IR2136STR monitors the motor current and keeps the switching of the motor in a safe range. It also has overload and short circuit protection for extra reliability.

How It Works

The IR2136STR features two channels, each of which contains a high-side and a low-side gate driver circuit. These four channels are referred to as ‘on’ and ‘off’, and are designed to drive two bilateral MOSFETs. The IR2136STR features a control logic, allowing it to be operated in a variety of modes, providing flexibility for many applications. These modes are able to be configured via the integrated registers.The control logic circuit enables independent operation of the channels, allowing one channel to remain powered while the other is powered down. This enables intelligent power management of the device and conserves power when in idle. The integrated PWM generator is also enabled, allowing the user to program the desired PWM frequency. The PWM duty cycle is then adjusted based on the desired speed and torque. This allows the user to easily integrate the device into a control system. The IR2136STR also includes various protections, such as overcurrent and short-circuit, providing robustness and reliability in power switching applications. Overall, the IR2136STR gate drivers offer flexible, high performance operation for powering motors in a wide range of end product applications. It is ideal for automotive, industrial, home applications, and other applications requiring high capacity switching, control, and reliability.
