LP8867QPWPRQ1 is a kind of highly-integrated, 4-channel 120-mA automotive LED driver. This passage is going to cover the perspectives of its datasheet, pinout, manufacturer, and features.

LP8867QPWPRQ1 Description

LP8867QPWPRQ1 is an automotive highly integrated, low-EMI, easy-to-use LED driver with a DCDC converter. The DC-DC  converter supports both boost and SEPIC mode operation. The device has

four or three high-precision current sinks that can be combined for higher current capability.

The DC-DC converter has adaptive output voltage control based on the LED forward voltages. This

feature minimizes the power consumption by adjusting the voltage to the lowest sufficient level in all conditions. For EMI reduction DC-DC  supports spread spectrum for switching frequency and an external synchronization with a dedicated pin. A wide-range adjustable frequency allows the LP8867QPWPRQ1  to avoid disturbance for the sensitive frequency band.

The input voltage range for the LP8867QPWPRQ1  is from 4.5 V to 40 V to support automotive start-stop and load dump conditions. LP8867QPWPRQ1  integrates extensive fault detection features.

LP8867QPWPRQ1 Functional Models

 LP8867QPWPRQ1 has 5 states totally.

① STANDBY State

The LP886x-Q1 enters STANDBY state when the VIN voltage powers on and voltage is higher than VINUVLO rising threshold, which is 4-V typical. In the STANDBY state, the device is able to detect VDDIO/EN signals. When VDDIO/EN is pulled high, the internal LDO wakes up and the device enters into a SOFT START state. The device will re-enter the STANDBY state when VDDIO/EN is pulled low for more than 50 µs.

② SOFT START State

In the SOFT START state, Power-line FET is enabled, and boost input and output capacitors are charged to VIN level. VIN_OCP, VIN_OVP, VIN_UVLO, SW_OVP, and TSD fault are active. After 65 ms, the device enters into the BOOST START state.

③ BOOST START State

In the BOOST START state, the DC-DC controller is turned on, and boost voltage is ramped to the initial boost voltage level with a reduced current limit. VIN_OCP, VIN_OVP, VIN_UVLO, SW_OVP, and TSD fault are active in this state. After 50 ms, LED outputs to do a one-time detection on grounded outputs. Grounded outputs are disabled and excluded from the adaptive voltage control loop. Then the device enters into a NORMAL state.

④ NORMAL State

In the NORMAL state, LED drivers are enabled when the PWM signal is high. All faults are active in this state. Fault pin will be released high in the start of NORMAL state if recovering from FAULT RECOVERY state and no fault is available.

⑤ FAULT RECOVERY State

Non-LED faults can trigger a fault recovery state. LED drivers, boost converter, and power-line FET are all disabled. After 100 ms, the device attempts to restart from the SOFT START state if VDDIO/EN is still high.
