SNVSD24 August 2025 LP5814I
PRODUCTION DATA
The LP5814I supports 8-bit PWM dimming with 23kHz frequency in both manual mode and autonomous animation mode. The device integrates an internal 6MHz oscillator to generate the PWM clock.
The LP5814I allows users to configure the dimming scale as exponential curve or linear curve for each channel separately through the OUT0_EXP_EN, OUT1_EXP_EN, OUT2_EXP_EN and OUT3_EXP_EN in DEV_CONFIG3 register. A human-eye-friendly visual performance can be achieved by using the internal exponential scale. The linear scale has great linearity between PWM duty cycle and PWM setting value, which provides flexible approach for external controlled gamma correction algorithm. The 8-bit linear and exponential curves are shown as Figure 7-2.
