Part Number: PCF8575
For PCF8575, how to estimate the power consumption of the pins, which are used as output GPIO?
Is Ioh the parameter to use?
In the data sheet, Ioh appears in several places with different value:
6.1: -4mA +-100mA (so big?)
Part Number: PCF8575 Dears,
Thanks for your support in advance.
1. Below is the Block Diagram of PCF8575 from datasheet( I marked 1,2,3 three MOSFETS,), in my understanding this P-port is push-pull output (MOSFET2 and MOSFET3),
my question is: when configure…
Hi Bobby Thank you for the reply. Yes. I found the root cause of the problem. We have connected a pull-up resistor on the line between the TPS26625 and the PCF8575. This pull-up resistor is falsly connected to 3.3V and this caused the wrong voltage level…
Part Number: TPS2662 Other Parts Discussed in Thread: PCF8575 Hello
I have a custom board on which the FLT pin of the TPS26625 is directly connected to an IO-Expander PCF8575 input. There is no additional resistor in line or a pull-up or pull-down resistor…
Part Number: PCF8575 Hi,
HTOL is not mentioned in the reliability test results. I have no doubt that the test result is "PASS", but I need to answer the customer.
Could you please provide the following information? "Min lot qty" "SS / lot" "Condition…
Part Number: PCF8575 Other Parts Discussed in Thread: C2000WARE , Hello, I am developing the driver for IO expander PCF8575. The spec says the writing address is 0x40 and the reading address is 0x41. But I scanned the I2C device and got the slave address…
Part Number: PCF8575 In our products we use PCF8575PW, but due to unavailability am not able to find the part.
What is difference between PCF8575.PCF8575C,PCF8575D ?
Can you suggest PCF8575 replacement ?
Part Number: PCF8575 I am trying to determine the markings on a pair of PCF8575 IC's to confirm if they are functionally equivalent. Both are TSSOP-24 packages.
One IC is marked
The other is marked
I understand the…
Part Number: PCF8575 I have a few questions:
First, what's the default mode of all the pins P0-P7 and P10-P17 after powered up.
Second, it is about the pins' mode. Based on the description in section 8.4, Device Functional Mode, of its data sheet…
