I have a signal on the input of an IC that is held high by a pull-up resistor. The same signal is connected to the output of a D-flip flop. This enables me to Clock a 0-value on to the flip flop output and drive the signal in question low. Driving the signal in question low will result in VCC to...
I anticipate a problem using D-flip flops in my circuit and powering up my system where i don't know what state the flip flops are in after the power up. I was wondering if i could implement a simple power-on-reset like shown below in order to ensure the flip-flops always powering up in a reset...
Hi again,
I am currently using a INA219 IC to measure the power consumption in a system. My problem is that the INA219 only has 16 usable addresses and i need 24 or more. The system has 8 modules and each module needs the power measured in three different places.
1. Is there an alternative to...
Thanks a lot for the help!
The forward voltage drop of the MBR0520L should be less than 300mV @ 100mA and the circuit that is powered through these diodes should not consume more than 80mA.
Do you have an example? I am looking for as simple a solution as possible with minimal chance of...
Can I power an IC form both 3.3v and 5.0v using the following setup:
Given that the IC can have an input range of 3-5v ofcource. I want to ensure the IC has power regardless of if only one or both of the voltages are present. Should I add a decoupling capacitor?
In case anyone else wonders. The conclusion is that an In-Circuit Serial Programming tool is required in order to raise the voltage of the EEPROM to the required level for programming.
Hi,
I have a project where i want to make use of the MCP25020 CAN bus IO-expanders from Microchip. It basically lets me read and write to a set of GPIOs from a can bus. I was wondering if it was possible to program the MCP25020 using the CAN bus? The datasheet (section 8.7) mentions In-Circuit...
Hi,
I am looking for literature on basic arithmetic function implementations or architectures. Like what you would find in an Arithmetic Logic Unit. I would like to know more about different implementations of things like addition, subtraction, multiplication, division, root and exponentiation...
