I am Evaluating DRV2625EVM-MINI Evaluation Board with an Linear Resonant Actuator whish spécification are:
-Thermal Resistance: 15.3Ω
-Power Consumption: <300mW @2.23Vrms(Sine Wave)
-Response Time <30ms
Following this Specifications, i have to set Drive Time to 1/(2*Fact)=5ms (see DRV2625 Datasheet at Page 23). But DRIVE_TIME Registor can hold a maximum Drive Time of 3.6ms (see page 54)
I also Have to Set RATE_Voltage register to 0x64 Value as motor Rate voltage is 2.23Vrms. The Clamp Voltage is 2.23*sqr(2)<3.16V so I have to set CLAMP_VOLTAGE register to 0x95 Value.
Please see attached Data for other value that i use for other configuration registers.
Now, when i run Calibration Process (1000ms), the process failled with none Over-current, Over-Temperature or under Voltage detection. The Diagnostics Process also failled with None Error detection.
Am I done something Wrong? How can i Fixed these issues?
