Part Number: SN74HCS273 Other Parts Discussed in Thread: UCC27517 Hi team,
My customer want to drive the gate of a FET by each output of SN74HCS273 directly. Their supply voltage is 3.3V.
The load(gate) capacitance is much higher than 50pF discribed in…
Part Number: MCF8316AEVM Other Parts Discussed in Thread: MCF8316A Hi Team,
EVM cannot drive the motor to work normally.
1. Run MPET can only measure resistance and inductance and cannot automatically measure MPET_KE.
2. After exiting MPET mode, the motor…

Part Number: DRV8462 Hi Team,
When STEP inputs a low-frequency signal, the motor operates normally. When STEP increases to a certain frequency, the motor will not be able to rotate and will make noise. Would you help to check it?
Best regards,

Part Number: LM5145DESIGN-CALC Other Parts Discussed in Thread: LM5145 Hello team,
I have a question about LM5145 design calculator.
MOSFET loss curve doesn't change when I change Qrr value of Low side FET. Only efficiency curve is changing by the parameter…
Part Number: DRV2605 On a project that has sold hundreds of units, we occasionally have an electrical board fail, with the symptom that the motor no longer vibrates.
We've carried out a number of investigations and have come to the conclusion that in…
