The L6219R is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors.The L6219R with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system.The power stage is a dual full bridge capable of sustaining 10V and including four diodes for current recirculation. A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction. An internal pulse-width-modulation (PWM) controls the output current to 500mA with peak start-up current up to 1A. Wide range of current control from 500mA (each bridge) is permitted by means of two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction. A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits. https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2020-06-06 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2021-04-02 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2021-07-16 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2021-12-03 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2022-04-10 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2022-06-12 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2022-06-24 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2023-12-15 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-01-18 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-07-31 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-08-09 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-10-26 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-11-22 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2024-12-10 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-01-15 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-03-02 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-04-08 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-04-17 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-05-11 https://elecena.pl/product/16950301/e-l6219r013tr-stepper-motor-driver 2025-05-21
