LP8863ADCPRQ1 +BOM

LP8863-Q1 Automotive Display LED-Backlight driver with Six 150-mA channels

LP8863ADCPRQ1 Information

Description

The LP8863ADCPRQ1 is a versatile LED driver from Texas Instruments, designed for automotive lighting applications such as headlights, interior lighting, and instrument clusters. It can also be used in other lighting applications where precision dimming and control of LED brightness are required. This device features six 150-mA channels, making it suitable for driving multiple LEDs simultaneously. It has a wide input voltage range, low dropout voltage regulator, and soft-start transient reduction to ensure stable operation. Additionally, it includes a dual-channel SAR ADC (12-bit x 2) with up to 100ksps sampling rate, allowing for precise monitoring of LED brightness. The LP8863ADCPRQ1 also features thermal shutdown protection, auto-recovery from overtemperature events, and fault-tolerant operation to ensure reliable performance in harsh environments. Its compact HTSSOP-38 package makes it suitable for space-constrained applications.
