The Texas Instruments LP8867QPWPRQ1 is a highly-integrated, low-EMI, automotive-grade LED driver IC. It is designed for applications requiring precise LED current control and offers multiple features for robust operation.
This device integrates a DC-DC converter that supports both boost and SEPIC topologies, enabling flexible power management for LED strings. It provides four high-precision current sinks, each capable of delivering up to 120mA. The outputs can be combined externally for higher current requirements per string. The input voltage operating range is from 4.5V to 40V, with an output voltage capability up to 45V.
Key electrical characteristics include a switching frequency range of 300kHz to 2.2MHz and a high dimming ratio of 10,000:1 at 100Hz via PWM control. The device includes comprehensive fault detection and protection mechanisms, such as input voltage overvoltage (OVP), undervoltage lockout (UVLO), overcurrent protection (OCP), boost switch OVP, output OVP, and LED open/short circuit detection. It also features power-line FET control for battery bus protection and automatic LED current reduction with an external temperature sensor.
The LP8867QPWPRQ1 is supplied in a 20-pin HTSSOP package suitable for surface mounting. It operates within an ambient temperature range of -40°C to 125°C (TA). This component is AEC-Q100 qualified for automotive applications and is functional safety capable, making it suitable for demanding automotive designs.
