  RE: p2p reset IC

  Dustin, Please check out the TPS312x family which is the low-power family you are looking for. TPS3125 (push-pull) and TPS3136 (open-drain) will both work. I believe TPS3126E18DBVT is the exact device you are looking for. Please let me know...

  RE: How to implement reset logic on the OMAP-L138 DSP core?

  Hi Mitesh, Asserting RESET without simultaneously asserting TRST will incur a warm reset, not a POR (power on reset) - is that what you want? Refer to 6.4.2 Warm Reset of the datasheet . A warm reset provides a limited reset to the device. Warm Reset...

  RE: TPS3824: How sensitive is TPS3824 to WDI transitions while asserting nRESET?

  The nRESET assertion time requires 25 us for a reset caused by voltage at VDD. The WDI pin recognizes pulse with width greater than 100 ns. This should give you the timing required to estimate the sensitivity at the moment reset is asserting and a watchdog...

  RE: TPS3125L30DBVR

  Hi Ahmed, You are correct that these two devices have different Vdd operating ranges. The cross reference search appears to be in error and will be corrected. Please note that a Vdd of 5V exceeds the Abs Max range for Vdd of TPS3125. As a result,...

  RE: How to adjust output PWM of UC3825

  Siyu, I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty. Go to page 43 and 44 of the attached and select a more suitable part.
