Part Number: DRV411 Dear Sir/ Madam,
We are building a project having the title: " Closed - Loop Hall Effect Sensors for DC Residual Ground Fault Current Detection"
Exact Current to be sensed is : 20 mA DC Current
I have read the Datasheet and…
Part Number: DRV411 Dear TI engineer,
In the datasheet, I saw that the output voltage of the H bridge can reach 5V which is the VDD of DRV411 when the compensation current is small (R_load is very high). I can't understand it because I think that the…
Part Number: DRV411 Hi TI engineer,
If I want to drive the compensation coil 250mA current and the voltage between the compensation coil is 4.2Vpp, the compensation coil resistance + the resistance of RSHUNT must be small than 4.2V/250mA=16.8Ω. …
Part Number: DRV411 Other Parts Discussed in Thread: DRV421 Dear TI,
could you please provide me the input bias current and input offset current informations of the differential amplifier used to measure the current on compensation coil?
Thanks!

Hello Yutong,
The voltage on the DRV411 is relative to its GND pin. Not GND itself. So below are Voltages referenced to GND.
VDD = 15V referenced to GND
VSS = -15V referenced to GND
5V = -10V referenced to GND
GND pins on DRV411 are connected to VSS so…
Other Parts Discussed in Thread: MSP430G2553 , DRV421 , DRV411 , DRV401 , TMCS1101 Hi,
We have designed a LED dimmer circuit and working on improving the circuit to detect the overload and short circuit condition to protect the switching Mosfets and the load…
Part Number: DRV411 Other Parts Discussed in Thread: DRV5053 , DRV425 , DRV421 , ADS1247 , ADS124S08 Does TI offer a DRV411 solution that allows for the sampled Hall output voltage - without using the closed loop portion of the design?
Essentially I am looking…
Part Number: DRV401 Other Parts Discussed in Thread: DRV411 Hi expert,
I'm trying to understand how DRV401 can co-work with my magnetics and probe design.
DRV401 offers IS1/IS2 as probe interfaces however it doesn't mention how the probe should be…
Part Number: DRV411 Other Parts Discussed in Thread: DRV401 Hi There,
I am trying to use the DRV411 in the 20-pin SOIC package on my benchtop to prototype a closed loop current sensor. Since I am using an off-the-shelf SOIC to PDIP protoyping board, there…
