JAJSOY5A may 2023 – august 2023 LP5861T
PRODUCTION DATA
LP5861T requires an external capacitor CVCAP, whose value is 1 μF connected from VCAP to GND for proper operation of internal LDO. The external capacitor must be placed as close to the device as possible.
TI recommends 1-μF capacitors to be placed between VCC / VLED with GND, and 1-nF capacitor placed between VIO with GND. Place the capacitors as close to the device as possible.
Pullup resistors Rpull-up are requirement for SCL and SDA when using I2C as communication method. In typical applications, TI recommends 1.8-kΩ to 4.7-kΩ resistors.
To decrease thermal dissipation from device to ambient, resistors RCS an optionally be placed in serial with the LED. Voltage drop on these resistors must leave enough margins for VSAT to ensure the device work normally.
