ZHCSGN5B March 2017 – July 2018 LP8863-Q1
PRODUCTION DATA.
The LP8863-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 or automatic detection. If a serial interface is available then extended configuration is possible. The configuration registers can be written in standby state as shown in Table 9.
REGISTER NAME | FUNCTION |
---|---|
BRT_MODE | Selects PWM pin or DISPLAY_BRT register for brightness control. |
SHORTED_LED_THRESHOLD | Selects voltage level for shorted LED Fault. |
DITHER_SELECT | Selects up to 3 bits of PWM dither for added dimming resolution. |
EN_MIN_PWM_LIMIT | Enables 200-ns PWM pulse limit and frequency dither to reach lower minimum brightness levels. |
SLOPE_SELECT | Selects duration for linear brightness sloper. |
ADV_SLOPE_ENABLE | Enables advance sloper S-shape smoothing function. |
DIMMING_MODE | Select between PWM, hybrid or current LED ouput dimming types. |
TEMP_MON_EN | Enables temperature window monitor function. |
TEMPERATURE_LIMIT_HIGH | Sets HIGH threshold level for temperature window function. |
TEMPERATURE_LIMIT_LOW | Sets LOW threshold level for temperature window function. |
