Part Number: DRV8412 Dear TI experts,
My customer now tests their own PCB with DRV8412. Could you review the schematic below?
The problem is, they use this circuit to operate peltier.
if the duty of PWM is under 50%, it is okay. (about under 5A current…
Part Number: DRV8412 Other Parts Discussed in Thread: DRV8876 Hello -
We are using the DRV8412 in our EndoVascular Robot and seeing some overshoot in the PWM output voltage that we are trying to understand and control. I've been trying to develop a spice…
Hi Michael,
The 1 second wait time is to ensure the driver has enough time to decay the current from the inductive load and any other parasitic inductances in the current path. If this wait period is ignored, it is possible that the device will quickly…
Part Number: DRV8412 Hello,
In the datasheet it says "In CBC current limiting mode, the detector outputs are monitored by two protection systems. The first protection system controls the power stage in order to prevent the output current from further…
Part Number: DRV8412 Other Parts Discussed in Thread: DRV8962 , , DRV8462 Hello, on DRV84x2 there is OC_ADJ pin to set current limit by resistor to AGND. Is it possible to use it as a variable current limit by appling external voltage or current by DAC…
Part Number: DRV8412 According to DRV8412 datasheet (p13), "In OC latching shut down mode, the CBC current limit and error recovery circuits are disabled and an overcurrent condition will cause the device to shutdown immediately. After shutdown, RESET_AB…
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…
Part Number: DRV8412 Other Parts Discussed in Thread: DRV8962 , DRV8952 , DRV8262 Hello,
I have an application where I need to drive a thermoelectric cooler, both for heating and cooling. 24V nominal. Current is 4.5A typ, 5.4A maximum. I will be driving…
Part Number: DRV8412 Dear Sir/Madam,
Please advise whether it is recommended/advisable to use DRV8412 to drive 2 TECs simultaneously (up to 3A each), in mode 4 (dual full bridge mode, one PWM input for each full bridge with complementary PWM on second…
