  • DRV8412: DRV8432 Some problems appear in the process of use, I hope to answer.Thank you.

    Part Number: DRV8412 Tool/software: 1. How to set up CBC and OCL mode? Can I only use CBC mode alone and turn off the overflow self-locking? 2. Monitor which position can well monitor the overcurrent protection, and which position with the oscilloscope…

  • DRV8412: LC filter for TEC drive

    TI Thinks Resolved
    Part Number: DRV8412 When using the DRV8412 to drive a TEC element, is it advisable to use polarized caps like an Aluminum Polymer Electrolytic for the LC filter between the driver output and the TEC? Design might need a large ceramic capacitor due to…

  • DRV8412: Any potential power saving could be made in reducing Vdd below 10.85v and if so to what value?

    Part Number: DRV8412 Tool/software: e2e, I seem to have observed a higher current through the Vdd vs. what is published in the datasheet [10.5mA at 400KHz 50% duty]. I measured an RMS current of 68mA driving a load at 300KHz with a 25% duty cycle…

  • DRV8412: OC Latching

    Resolved
    Part Number: DRV8412 Based on Section 7.4 from the DRV8412 datasheet, it appears that only Mode 2 features an OC latching shutdown. However, the response to the linked E2E forum post suggests that OC latching shutdown occurs in all operating modes…

  • DRV8412: Plobems with DRV8432

    Resolved
    Part Number: DRV8412 Hello, My name is Javier, We have a system to control two light signals at “220Vca/50Hz” based on the DRV8432DKDR. Technical data VREG =3,34V VDD = 12V PVDD_A = PVDD_B = VCC from 21V to 27V PVDD_C = PVDD_D = VCC from…

  • DRV8412: The changes of footprint?

    Resolved
    Part Number: DRV8412 We purchased a reel of DRV8432DKDR (75 pcs) from a local retailer, and we faced similar problems as this thread: DRV8432： Appearance changes? - Sensors forum - Sensors - TI E2E support forums In the 8432EVM we bought, it is like…

  • DRV8412: Can the output pull down resistor dissipate excessive power when a inductive load discharges frequently with /reset being low?

    Part Number: DRV8412 Lets assume power supply is 48v and a inductive load that takes 100e-6s to decay to zero current when /reset input goes low repeating every 250e-6s. This means a power of 2.3W dissipated in one half bridge pulldown with a duty cycle…

  • DRV8412: DRV8412

    Resolved
    Part Number: DRV8412 Hi, I 'm using the DRV8412 driver in parallel full bridge mode but no truth table is provided about how the output is controlled. I'm particularly interested in the truth table for the parallel full bridge mode of the device. Thanks…

  • DRV8412: Unexpected OC Latching Shutdown

    Part Number: DRV8412 Hello, we are currently troubleshooting our DRV8412 design because we are experiencing latching shutdowns while driving a stepper motor at currents of greater than 3A. I believe we have eliminated undervoltage protection as the…

  • DRV8412: DRV8412 partial damage: no output in first output channel

    TI Thinks Resolved
    Part Number: DRV8412 Hi, We are debugging DRV8412 board. But I found DRV8412 went to following damage status sometimes: The first output channel (Pin5-7) is abnormal - No PWM output. But the second output channel (Pin15-17) is normal output with PWM…
