Each full-bridge output is rated up to A and 40 V. The A includes fixed off-time pulse-width modulation (PWM) current regulators, along with 2- bit nonlinear DACs (digital-to-analog converters) that allow stepper motors to be controlled in full, half, and quarter steps, and DC motors in forward, reverse, and coast modes. The L device is a DMOS dual full bridge designed for motor control applications, realized in BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device also includes two independent constant off time PWM current controllers that performs the chopping regulation. Full-Bridge DMOS PWM Motor Drivers A and A Allegro MicroSystems, LLC 5 Northeast Cutoff Worcester, Massachusetts U.S.A. ; www.doorway.ru Functional Description Device Operation The A and A are designed to operate DC motors. The output drivers are all low-R DS(on), N-channel DMOS drivers.

The A includes fixed off-time pulse-width modulation (PWM) current regulators, along with 2- bit nonlinear DACs (digital-to-analog converters) that allow stepper motors to be controlled in full, half, and quarter steps, and DC motors in forward, reverse, and coast modes. Each full-bridge output is rated up to 1 A and 18 V. The AMT includes fixed off-time pulse-width modulation (PWM) current regulators, along with 2- bit nonlinear DACs (digital-to-analog converters) that allow stepper motors to be controlled in full, half, and quarter steps, and DC motors in forward, reverse, and coast modes. Full-Bridge DMOS PWM Motor Driver: Description: Designed for pulse width modulated (PWM) control of DC motors, the A is capable of peak output currents to ± A and operating voltages to 40 V. Input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals.


products Motion Motor Control ICs are electronic devices which control or drive motors from MOSFETs to highly efficient internal DMOS motor drivers. The AELJTR-T is a full bridge DMOS PWM motor driver in 8 pin NSOIC package. It is designed for pulse width modulated (PWM) control of DC motors. FULL-BRIDGE PWM MOTOR DRIVER. Data Sheet OFF-time PWM current-control circuitry can be used to regulate the 3-Phase Controller/DMOS Driver.
