  • DRV8835: How to use drv8835 to drive magnetic latching relays?

    Part Number: DRV8835 Tool/software: Hi, I plan to use drv8835 to drive magnetic latching relays. I have some questions: Can one channel of DRV8835 (max current 1.5A) drive 16 relays like G6KU-2F-Y-TR-5VDC (current 21.1mA)? Does the circuit need additional…

  • DRV8835: DC motor reverses the direction when the power is low

    Part Number: DRV8835 Hi TI Technical Support Team, I have designed a board to control 2xDC motor (3-6V hobby DC motor, each motor draws 150 - 200mA at max) using DRV8835. The board is powered from 3.7V 1000mAh LiPo battery and I am using buck and boost…

  • DRV8835: EMC radiated test issue 185MHz

    Part Number: DRV8835 Dear support team, We develop a new product with this nice part but now have EMC issues. Using near field probes we identified this component as a source of ~185MHz (charge pump?). As there are no details in datasheet that could help…

  • DRV8835: Design issues

    Part Number: DRV8835 Hi Team, Customer would like to know: How to control the motor to rotate when MODE is high level (ie PHASE mode)? Among them, AIN1/APHASE_1, AIN2/AENEL_1, BIN1/BPHASE_1, and BIN2/BENEL_1 are all GPIO modes. Thanks, Annie
