Part Number: TSS521 Hi
What's the difference between TSS721 and TSS521? Is there a migration guide about this?
My customer use TSS721 on their previous product. They are searching for cost down solution recently.
Part Number: TSS521 Team,
Using the device per Figure 9 from the datasheet (Basic Optocoupler Application). C_STC = 150uF, R_RIDD = 20kR.
In the datasheet, the example with Figure 6. (Basic Application Circuit With Support Capacitor C_STC > 50uF)…
Part Number: TSS521 Hi,
in the datasheet of TSS521, we detail protection resistors of 220 ohm at the bus terminals. How can my customer determine if indeed 220 ohm are required or some other value might be more suitable? Specifically, my customer is…
Part Number: TSS521 Other Parts Discussed in Thread: TSS721A Hi,
I have been studying data sheets of TSS521 (and TSS721A) to prepare for a design project starting next week.
I am worried about connections to unused data pins, as the data sheet doesn…
Part Number: TSS721A Other Parts Discussed in Thread: TSS521 , , MSP-PMBUS , MSP430-SMBUS hi dear supporting team,
besides TX, TXI current difference, what's the other difference btw 721 and 521? And do we have other M-BUS solution without getting power…
Other Parts Discussed in Thread: TSS521 Hi Champs,
My customer want to use TSS521 in industrial related product, which requires -45~85℃ operating temp. From datasheet, we can know the operating temperature is -20~85℃. So my question is can we provide…
Other Parts Discussed in Thread: TSS521 Hello Team
My customer is working on TSS521 for the water meter application and has below question. Could you please help?
Please see attached the schematics of TSS521. The Figure 8 on the TSS521 datasheet…
Ryan,
Thank you for your reply. Now I have discovered the reason of the problem I encountered before. The level of mbus master I use is +15V and -15V, so when TSS521 switches in mbus, GND of TSS521 is about -15V. If GND is shared between TSS521 and…
Hi Umut,
1. Based on Figures 6 & 7 of the TSS521 datasheet I would connect UCA0RXD to TXI and UCA0TXD to RXI. The difference, as Figures 1 & 2 show, have to deal with the inactive state of the line so if using normal USCI operation you want the lines…
