Hi Team,

Currently, we plan to use AUTOCRANKSIM-EVM (HVAL068A)

Here I attached the waveform which we want to generate from it.

Questions:

Can It generate the attached waveform or suggest another solution for generating the waveform?

As per our attached waveform & Voltage range.
Required Output Voltage range is 2 to 28.5V dc.
Please confirm Out voltage range of EVM: AUTOCRANKSIM-EVM (HVAL068A).
In User guide “HVL068A Cranking Simulator User's Guide”
Output Voltage range is 2 V to 15 V dc.
Can we change it? Please give suggestions for it.

please provide prices & Delivery period.

Hello Chintan,

this tiny generator is based on a buck converter using TPS40170 and a VID interface to control the output voltage;
the I/Os of the uProc MSP430 are controlling the voltage itself by switching weighted resistors in parallel
at the feedback divider, please check schematics.

For using our EVM up to 29Vout (needs >32Vin) you need to make a redesign regarding input bulk capacitor, FET's,
3V3 bias regulator and output capacitors to w/stand the higher voltages.

Best regards, Bernd

Hi Bernd,

Can we modify hard-programmed cranking puls ("DaimlerChrysler Engine-Cranking Test Pulse, DC-10615") according to our requirement?

Hello Chintan,

YES, if you change the hardware to input voltage 32V you can program any waveform in between 2V to 28.5V output range,

best regards, Bernd
