JAJSJG4B August 2020 – May 2024 LP8864S-Q1
PRODUCTION DATA
The LP8864S-Q1 does not require any serial interface configuration. It can be simply controlled with the EN pin and PWM pin. Most of the device configuration is accomplished using external resistor values. If I2C interface is available then extended configuration is possible. The configuration registers can be written from standby state to normal state as shown in Table 6-10.
REGISTER NAME | FUNCTION |
---|---|
ADV_SLOPE_ENABLE | Enables advance sloper S-shape smoothing function. |
DITHER_SELECT | Selects up to 3 bits of PWM dither for added dimming resolution. |
SLOPE_SELECT | Selects duration for linear brightness sloper. |
BRT_MODE | Selects PWM pin or DISPLAY_BRT register for brightness control. |
SPREAD_RANGE | Selects up to 2 bits boost switching frequency spread spectrum range. |
SPREAD_MOD_FREQ | Selects up to 2 bits boost switching frequency spread spectrum modulation frequency. |
SPREAD_PSEUDO_EN | Enables pseudo random modulation for boost switching spread spectrum frequency. |
