  TPS22943: Will it be it okay if "ON" pin enabled prior to “VIN” power on？

  TI Thinks Resolved

  Part Number: TPS22943 Dear TI, Here we have a special application occasion that TPS22943 will be enabled prior to "VIN" power on, will it be okay? Any risk? Thanks.

  TPS22943: Load switch with protection and very Low Iq - needed

  TI Thinks Resolved

  Part Number: TPS22943 Hi, I am designing a water meter product that runs on a battery. I have an external flow sensor that takes very less operating current (<1mA). Since this sensor is installed externally, I want to protect my electronics from...

  RE: TPS22942: Clarifying ON pin function, datasheet is ambiguous

  Hi Alex, Thanks for reaching out on E2E! Since the TPS22942 datasheet is used across all of our TPS2294x devices (TPS22941, TPS22942, TPS22943, TPS22944, and TPS22945), there will be some overlap information in the Applications Section of the datasheet...

  RE: Low current limited load switch - adjustable current limit

  Hi Alex, Do you need to be able to adjust the current limit over the whole range (10mA-100mA), and how much accuracy is needed? Also, are you needing to adjusting the current limit during operation? For that range, the TPS22946 might be a good...

  RE: current limit of the current-limited load switch

  Hi Tamas, You are correct that the output current limit of the TPS22944 could be as high as 200mA. 100mA is the lowest the current limit will be; guaranteeing at least 100mA downstream. From the typical graph in Figure 11, the expected current limit...

  RE: UCC3806 reference design and simulation model

  Hello, The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose...

  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.
