Part Number: LP8501 Hello,
in some cases the supply in our system can drop to 2.5V. We know that this is out of spec and don't expect the device to meet the datasheet.
As this only occurs rarely we still want to understand the implications of it.…

We become indebted to. I2C SDA signal output delay value not found in data sheet. Please tell me the output delay time and output hold time of SDA with respect to SCL when reading the register. Could you describe the timing chart…

Hi
Please let me ask the relation ship between CP_MODE bit and CHP_CON bit.
From the description in CP_MODE bit, the battery voltage is connected to the current sources, then does it mean that the CHP_CON setting is ignored…
Part Number: LP8501 Hi all
My customer is using the LP8501 and they want to verify what measure they can take in case the I2C-bus gets stuck.
Is toggling the EN-pin a way to reset the bus ?
Morover my customer wants us to test and document any…
Other Parts Discussed in Thread: LP8501 Hi,
About the interrupt of the LP8501 In the STATUS / INTERRUPT register ENGx_INT When BIT is set, it is output from the INT terminal. Which of the following conditions (1) and (2) is correct? (1) When ENG1, ENG2…
Other Parts Discussed in Thread: LP8501 , TCA9543A Dear all.
Our customer uses two LP8501's. Is it possible to share I2C port using EN pin?
Regards, PAN-M
Dear all.
Our customer is saying that Rise/Fall timing of I2C of this device is difficult. The minimum Fall timing is 15+0.1Cb ns. Our customer's Falling timing is 3ns, it's difficult to control this timing. Is this timing really necessary?
If this…
Other Parts Discussed in Thread: LP55231 , LP8501 , LP5523 Hello,
we want to use the LP8501 or the LP55231 to drive some white µLEDs. The LEDs should be switched On/Off with a frequency around 2kHz. If I understand the datasheet correctly the PWM…
Just another crazy thought ... not sure about your cost and size constraints, but the LP55231/LP8501 support 12-bit PWM, and proportional logarithmic dimming, so that you can get good colour matching right down to <1% brightness...
Hi Kris,
To help with the LED engine mapping etc. please take a look at the LP8501 programming considerations application note: http://www.ti.com/lit/pdf/snva715
LP8501 is very similar to LP5523 and the engine mapping etc. command set is compatible…
