Part Number: DRV8243H-Q1EVM Tool/software: When considering RPROPI values from DRV8243-Q1EVM, the ITRIP values will be in microamperes (µA). For a motor load current requirement of 3A, calculation using the maximum VTRIP value resulted in a very low RPROPI…
Part Number: DRV8243H-Q1EVM Other Parts Discussed in Thread: PCF8574 , ADS1115 , DRV8243-Q1 Tool/software: Hello Joshua, months ago I opened a thread "DRV8243H-Q1EVM: general configuration & layout revision".
I build some pcb boards according to schema…
Part Number: DRV8243H-Q1EVM Other Parts Discussed in Thread: DRV8243-Q1 Tool/software: Hi!
I want to combine the sleep/drvoff inputs and the fault outputs of two DRV824xH-motor drivers: one DRV8243H and one DRV8244H (see schematic, caps and pullups…
Hi JM,
Would you mind providing a block diagram of your application? I would like to check your load configuration. The DRV8243 cannot support parallel output on the same device. To achieve this the DRV8143 would need to be used.

Part Number: DRV8243H-Q1EVM Tool/software: We're using the DRV8243HQRXYRQ1 in a full-bridge configuration to drive an actuator. We've set the overcurrent protection to its maximum limit, but the device is tripping at 6.5A, significantly lower than our…
Part Number: DRV8243H-Q1EVM Other Parts Discussed in Thread: MSP430G2553 Tool/software: I am using DRV8243H-Q1 EVM. I am selecting 20KHz frequency but I am getting only 2.5KHz PWM output. I am getting proper frequency output at 10KHz, 5KHz and 2.5KHz…
Part Number: DRV8243H-Q1EVM I recently acquired the DRV8243H along with the EVM, and I'm encountering two issues:
Currently, the nFault is triggered when the ITRIP reaches 5A, and I'm struggling to adjust it to a different value. I've attempted…
Part Number: DRV8243H-Q1EVM Other Parts Discussed in Thread: DRV3946-Q1 Tool/software: I have started to evaluate the DRV8243 H variant for a project. I downloaded the simulation for it an run it, but when I look at the IPROPI voltage, it seems to go…
Part Number: DRV8243H-Q1EVM Is the rising edge of nFAULT only a sure indication for a ClearFault or also for a wake up during the NSLEEP pulse? The reason for the question is to minimize the time for the NSLEEP pulse, which is stated as 20µs to 40µs.…
Part Number: DRV8243H-Q1EVM Other Parts Discussed in Thread: LM74610-Q1 Hello everyone,
I have a DRV8243H-Q1EVM. When I connect a motor and operate the bridge with PWM, I have periodic voltage drops on the output side.
The signals can be seen on the…
