  • RE: Controlling Peltier element with an H-Bridge IC

    Hi Den., At 10kHz PWM and <5V, there are many options available. One option is the DRV8837. If you need to automatically control the current, the DRV8834 is a possible option. If you need higher PWM frequency, please let us know how high. Depending…

  • CCS/MSP430FR2111: Code porting ADC functionality from MSP430G2131 to MSP430FR2111

    Resolved
    Part Number: MSP430FR2111 Other Parts Discussed in Thread: DRV8837EVM , Tool/software: Code Composer Studio Hello, I am working with a motor driver evaluation module (DRV8837EVM) where I am replacing the existing MCU (G2131) with an FR2111. The idea is…

  • RE: DRV8837: motor is blocked, How to solve these problems in the intelligent door lock?

    Hi user, To select the sense resistor, you need to determine a voltage across the sense resistor that, when amplified by a current shunt amplifier, the amplifier's output is acceptable voltage for the receiving ADC of an MCU (e.g. sense resistor sees…

  • RE: DRV8837: What is the efficiency of DRV8837?

    Tzion, Thanks for the correction. I edited my typos in my previous post above and made a note. If you are using the TI EVMs for these devices, did you remove the STATUS LED from the DRV8837EVM? This will blink and sink current, which may account for…

  • [FAQ] Driving a Hobby Servo Motor

    Other Parts Discussed in Thread: DRV8876 , DRV8837 , DRV8837C , DRV8874 We drive all kinds of motors including Brushed, Brushless, and Stepper varieties. What about Servo Motors? Yes we are can include those as well. A servo like the one below has three input…

  • RE: DRV8837: Schematics Review

    Hello Kinjan, I only reviewed the DRV8837 portion of the schematic and it looks fine. The pulldown resistor on nSLEEP is fine, but it is not necessary since nSLEEP has an internal pulldown on that pin already. The 1000uF bulk capacitor is excessive.…

  • RE: CC3220: Reset every 5mins over and over again when testing the wifi door lock ref design

    Ben, thanks for reply. 1. I didn't change the broker, still "m2m.eclipse.org" . I just did a slight modification on the ref design code. for example: changed the time zone,disable some functions through the macro definition as below #define…
