Other Parts Discussed in Thread: DRV110 , TIDA-00284 , TIDA-00289 Hello,
I have a question for TIDA-00284 Reference Design with DRV110.
As my understanding, the resistor connected to HOLD pin of DRV110 used to set I HOLD current, and the equation…
Hi Girish,
Unfortunately, we don't have an exact replacement for the DRV102. After talking to the motor drive team, you could also take a look at the DRV110 or DRV8704 , which requires an external FET.
Additional, the DRV8844 can meet your voltage…
Hi Samuel,
It looks like your board is configured correctly. Is the DRV110 part outputting anything? You can check the OUT pin with an oscilloscope to verify the part is functional. The OUT pin will either be high or PWM when the EN pin is high.
If…
Vishnu -
Yes, TIDC-EVSE-WIFI (TIDA-00637 + CC3100BOOST) is still a relevant design to use as reference for Level 1 & 2 AC charging stations.
TIDA-010071 would be good design to reference below sub-system:
Pilot Wire detection - using TLV1805 and…
KPK,
The datasheet says the resistance of the OUT pin to ground is 1.7-2.5 Ohms. My educated guess, based on comparing the DRV110 and DRV120 datasheets, is that the sense resistance is 1-Ohm. The rest of the OUT pin resistance would be due to Rds(ON…
Hi,
Thank you for your interest in DRV120. DRV120 is not designed to control current by external voltage(DAC) input, just designed to set Peak and Hond with Rpeak/Rhold. However this link is gimmick to control current level externally. This is optional…
Of course, Alain thank you.
The Solenoid is a 5V, 1.8W MAC valve (BV210A-CA1-00-BKSA-CBA) L=15 mH (as measured)
I am concerned that the issue is occurring prior to the solenoid even being actuated, when the EN pin goes high (straight from MSP 430…
Hi Mehmet,
1) While some of our motor drivers do PWM on the output automatically, this one does not. If you want to use PWM with this device, you need to provide the PWM signal input from your NI DAQ. Anytime you vary the duty cycle of a square wave…
Hi Jimmy,
The subsystems needed depend on what kind of AC Charger with what features you want to build. For a home charger the metrology is not needed since there is no billing if you charge at home. In this case I would start with TIDA-010071 nd add…
Luc,
Sorry for the delay, I have been out of office.
It seems you are seeing that the IPEAK is not changing as a function of RPEAK between the range of 62kΩ and 80kΩ? What values of Rosc, Rpeak, and Ckeep? When you change Rpeak above 80kΩ, does the…
