Part Number: LP8864S-Q1 Tool/software: Hello,
We have a new acquisition project which is required function safety of backlight driver. We select LP8864S-Q1 in this project.
Has this device been designed in accordance to ISO26262 norms?
If yes, do you…
Part Number: LP8864S-Q1 Tool/software: Hi team,
In LP8864S-Q1, there is booster mode and SEPIC mode, what is the difference? Can SEPIC mode work on both booster mode and buck mode?
for example, in my truck project, battery voltage is 24V typical(16V…
Part Number: LP8864S-Q1 Tool/software: LP8864 application circuit is as below, it is used as power supply for TFT panel backlight. When LP8864 EN pin is offered 3.3V, 948_VDD_BL_20.58V output 19.6V. But if PWM pin has 305Hz pwm signal input, the backlight…
Part Number: LP8864S-Q1 Tool/software: Team,
what is the minimum achievable output current for a given ILED.
E.g. I set ILED=100mA. In theory by putting LED_CURR_CONFIG[11:0] = 01b I should be able to achieve 100mA / 4095 ~= 25uA.
Will the device support…
Part Number: LP8864-Q1 Tool/software: when I try to use I2C to write register SUPPLY_INT_EN, it failed. Does it need any extra steps before write this register? or Is there a configuration to enable writing this register?
Part Number: LP8864-Q1 Tool/software: I'm trying to read the error information from backlight chip registers when detecting error. But I only care about whether the error is caused by BSTOCP_STATUS, BSTOVPL_STATUS, SHORT_LED or OPEN_LED. I notice that…
Part Number: LP8864-Q1 Tool/software: I'm trying to read the error information in backlight chip register which is only triggered by BSTOCP_STATUS, BSTOVPL_STATUS or SHORT_LED. So how to only trigger one of these backlight errors without other erro…
Part Number: LP8864S-Q1 Tool/software: I shorted the LED output while testing the fault interrupt, triggering the LED internal short Status.The corresponding exception 0x484 was read from register 0x12, but after I removed the short circuit and wrote…
Part Number: LP8864S-Q1 Tool/software: hello, TI team
design specification：input=4V-16V
output=typ.34.1V, Max.35V
output current: 115mA*4
Phenomenon： the output is turned off →on→ off……when input is low voltage, for…
Part Number: LP8864-Q1 Tool/software: Hello support team,
We are now designing the schematic of LP8864, and we have a problem about the setting of Vboost.
Why should be set the max and min for VBoost?
If we set the R1=680K, and R2=42.2K, the VBoost_Max…
