  CSD17578Q3A: CSD17578Q3A 5*6 package

  TI Thinks Resolved

  Part Number: CSD17578Q3A Team, Looks like CSD17578Q3A doesn't have 5*6 package. Could you help recommend a MOSFET that has similar spec with 5*6 package? Thanks. Reagrds NIc

  RE: BQ25703A: Dual TPS65988 plus BQ25703A schematic review request

  Ok, thanks, we have done the schematic review and have a few questions. Could we have comments on the following? 1. C24 and C35 in our design is currently 33uF ceramic cap. The recommendation was 33uF tantalum. Because of space we used 1206 package...

  RE: BQ25703A: Low/High side N-MOSFET suggestion.

  Hey Hugo, The recommended replacement for the CSD1755Q3A is the CSD17578Q3A. The HIDRVx and LODRVx pins output up to 6V across the Gate-Source of the power MOSFETs. So MOSFETs with +/-10V to +/-20V rated VGS should be fine. Regards, Joel H

  RE: CSD17308Q3: Power NFET behaves like an SCR, won't turn off

  Hi Aaron, Anytime VGS exceeds the abs max rating of 10V, the gate oxide can be damaged. This can lead to a hard failure if the voltage is high enough or a cumulative failure if the device is exposed to multiple overvoltage events at lower voltages. Did...

  RE: CSD17578Q3A: How to estimate the max switching frequency

  Dong, While you are correct in theory, the reality is a bit more complicated. For one, rise times and fall times in MOSFET datasheets are historically unreliable and pretty useless parameters. I wrote a blog about this here: Secondly, when you approach...

  BQ25703A: BQ25703A output of VSYS_6V6_8V4 was not normal.

  Part Number: BQ25703A We encountered a problem of BQ25703A during debugging. After the TYPEC_5V was powered, the output of VSYS_6V6_8V4 was not normal. When testing, it was found that the REGN was sometimes 4V output and sometimes 6V output. What could...

  RE: BQ25708: 250ms oscillation through inductor

  I found the culprit.. the mosfet HIDRV_1 was shorted across drain and source. Using a CSD17578Q3A Replaced it, and no more click, plus the system now works as it should. Took a look at the gate drive to this device and its partner HIDRV_2, and I see ...

  RE: BQ25713: Advice on 4S4P Battery to charge

  Hi Mo, Regarding power MOSFET selection, the datasheet says that for applications with 19-20 V input, it's preferred to use MOSFETs with 30 V or higher voltage ratings. It doesn't mean that you have to use MOSFETs with specifically 19-20 V...
