Part Number: TPL9202 Other Parts Discussed in Thread: TPL7407LA
Tool/software:
Hi all.
I am designing a board that will be required to switch on many relays, hence I am using TPL9202 to do the work.
I have validated the psuedo-circuit on a single…
Part Number: TPL9202 Other Parts Discussed in Thread: ULN2803C , I observe that the datasheet recommends a supply of 7-18V. Unfortunately I only have a supply of 6V5 nominal. However, my output current is less than 40mA total at any one time, so I am…
I'm really sorry for prolonging this discussion to this extent ! Turns out the manner in which i was measuring the output was wrong ,which I realized after knowing that TPL9202 is of sink type .The BO wasn't an issue . I followed CB's advice of measuring…
John,
The ULN2803 has huge transistors that can handle a lot of current. However the Darlington output has a high VOL that will cause more self-heating. The ULN2803 package does not transfer heat nearly as well as PWP package.
For 8 channels on 100…
Other Parts Discussed in Thread: TPL9202 Hello,
I am planning to use two TPL9202 's to drive HE751A1200 relays from Hamlin and EV-2M-12 Solenoid Valves from Clippard. I am interfacing the TPL9202
to 5V SPI bus that have individual Chip Selects.…
Other Parts Discussed in Thread: TPL9201 Is it allowed to connect Thermal Pad to GND plane ?
In datasheet http://www.ti.com/lit/ds/symlink/tpl9201.pdf , Page 8, Figure 1. Serial Communications , you shall add a new line which would describe an update…
Other Parts Discussed in Thread: TPL9202 Hi, Simple question... Is it possible to parallel outputs of the TPL9202 to increase output current?
Thanks,
Bart
Loren,
There is production savings for 16 pins packages over 18. Also the ULN2003 is more popular than ULN2803. 8 channels may come but I don't have a time table. Perhaps the extra channels can be used as logic inverters or open collector NAND gate…
Other Parts Discussed in Thread: TXB0104 , TPL9202 , SN74LVC1T45 Hello,
I am planning to use TXB0104 to translate the signal level of SPI signals from 3.3V (from microprocessor) to 5V (for slave devices). There are 3 slave devices on the same SPI…
Mohd,
That data is available on the product page in the Quality & Environmental Data section. http://www.ti.com/product/ULN2803A The worst case VCE(SAT) is 1.4V (per data sheet). With 250mA, that is 350mW per channel. With a package TJA of 73C/W, the…
