Part Number: LP5522 Tool/software: Hello,
The datasheet shows that the recommended output current setting using RISET is 3-25mA:
But is it possible to use a higher RISET for output current in the range of 1-2mA? Is the concern just around accuracy…
Part Number: LP5522 I want to use this part as a dump, static current limit. From a reading of the spec, it seems that this is possible if I just tie CTRL high. Is this indeed the case? Please verify
thank you
Part Number: LP5522 Hi,
I have a custom board with the LP5522 being controlled using a microcontroller. The microcontroller is controlling the CTRL input pin and Iset is set using an external resistor. The LED output from the LP5522 is driving a LCD…
Part Number: LP5522 Other Parts Discussed in Thread: LP5560 Hi there,
I am looking for an LED driver which can drive the backlight of my display. The display light has a forward voltage of 2.4V and a current of 1 to 20mA based on how bright I want…
Part Number: TPS92612 Other Parts Discussed in Thread: LP5522 , , TPS92610EVM , Tool/software: Hello,
My customer would like to blink and LED at 0.5Hz (1 second on and one second off). They do not want to use I2C, and would prefer a resistor for setting…
Hi Junyoung,
The difference between TLC5973 and TLC59731 shown below.
At present, besides the TLC5973 and TLC59731 RGB led driver, only the LP5522 (Single channel programmable LED driver) support the 1-wire LED control.
But you may take a look at…
Other Parts Discussed in Thread: LP5522 , TPS92612 Hi all:
I am looking for a (3channel or single) indicator LED driver (Vf = 1.4V If= 10mA maximum). The control interface is 1.8V GPIO from MCU. But I can't drive the LED by GPIO directly. (the GPIO…
Hi Antonio,
Sorry for late reply that this week is our national holiday.
What is customer's application and requirements for channel number/output current/power supply and so on. We have LP5562/0, LP5522/3/4 in similar WCSP package.
Price information…
Calum,
What kind of package do you prefer? If an BGA is suitable for your application you could check out LP5524, which has 4 LED outputs 5mA default current and 2 channels for external PWM control. This in uSMD package.
There is also 1 LED output…
