NJM2611M is an integrated PWM motor driver integrated of buck operational amplifier and PWM regulator, which is optimally designed for motor control. It is a tiny package motor driver that fits into different motor drives applications. NJM2611M consists of an LDO regulator, a single buck operational amplifier and motor driver circuitry integrated in a single chip. It has a wide range of output current levels from 2A to 40A, with a 2.5V to 40V input voltage range. NJM2611M can be used for various motor drive applications such as DC motors, stepper motors, brushless DC motors, etc.

Application Field

NJM2611M can be used for various motor drive applications such as DC motors, stepper motors, brushless DC motors, and it\'s also suitable for applications with relatively low electrical load. In addition, it includes features such as over-current protection, over-temperature protection, over-voltage protection, over-frequency protection and under-voltage protection, so NJM2611M can be used in applications that require high accuracy and safety. Moreover, the NJM2611M can be used in automotive and metering applications due to its low power consumption and fast switching response time.

Working Principle

The NJM2611M motor driver consists of a buck operational amplifier, current limit voltage, over-voltage protection threshold, over-temperature protection threshold and an output enable function. When the NJM2611M is powered on, the voltage across the output enable pin is set to a value that is higher than the voltage on the enable pin. This will activate the power FETs, which will enable the output. The NJM2611M can then adjust the voltage and current to control the motor speed and torque. The buck amplifier will regulate the output current, while the current limit voltage provides an over-current protection. The over-voltage protection will protect the motor from over-voltage and the over-temperature protection will protect the motor from temperatures that are too high. NJM2611M also has the ability to operate in either a fixed duty-cycle or PWM mode, which all adds up to an overall efficient, reliable and safe motor driver.
