A3980KLPTR is a motor driver, controller and power management integrated circuit (PMIC) from Allegro MicroSystems. It is designed for motor and solenoid control applications. The device is suitable for operation up to microcontroller and digital signal processor (DSP) clock frequencies. It can support low voltage and high voltage motors, as well as multiple configuration modes.

The A3980KLPTR device offers additional short-circuit protection and adjustable current limit protection. It has an integrated host processor capable of managing peripheral operational and output characteristics in complex systems. The device includes a built-in system power supply regulator and includes adjustable voltage output and current limit.

The A3980KLPTR is a flexible, fully-integrated motor driver andcontroller suitable for operation in a wide range of applications. Its integrated circuit architecture enables easy configuration through an extensive set of programming registers. This device is capable of working with multiple, different external componentsand the power requirements for all of these components can be controlled accordingly.

A3980KLPTR features an integrated PWM generator, motor driver, and motor control logic. It also features dual full-bridge motor drivers and supports both independent and synchronous PWM control. The motor driver is capable of operating in both voltage-mode and current-mode control. In voltage-mode control, the voltage of the motor is always kept constant; in current-mode control, current is monitored and the voltage is adjusted accordingly.

The A3980KLPTR also includes a short-circuit protection which offers protection against output saturation and thermal overload. An adjustable current limit feature is available to protect against high current fault conditions. The device supports both manual and automatic shut down of the motor in case of an over-current or over-temperature condition.
