Description

The A8514 is a multi-output white LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and four current sinks. The boost converter can drive up to 48 LEDs, 12 LEDs per string, at 80 mA. The LED sinks can be paralleled together to achieve even higher LED currents, up to 320 mA. The A8514 can operate with a single power supply, from 5 to 40 V, which allows the part to withstand load dump conditions encountered in automotive systems.

Features and Benefits

• AEC-Q100 Qualified

• Wide input voltage range of 5 to 40 V for start/stop, cold crank and load dump requirements

• Fully integrated LED current sinks and boost converter with 60 V DMOS

• Sync function to synchronize boost converter switching frequency up to 2.3 MHz, allowing operation above the AM band

• Excellent input voltage transient response

• Single resistor primary OVP minimizes VOUT leakage

• Internal secondary OVP for redundant protection

• LED current of 80 mA per channel

• Drives up to 12 series LEDs in 4 parallel strings

• 0.7 to 0.8 LED to LED matching accuracy

• PWM and analog dimming inputs

• 5000:1 PWM dimming at 200 Hz

• Provides driver for external PMOS input disconnect switch

• Extensive protection against:

▫ Shorted boost switch or inductor

▫ Shorted FSET or ISET resistor

▫ Shorted output

▫ Open or shorted LED pin

▫ Open boost Schottky

▫ Overtemperature (OTP)

Applications:

LCD backlighting or LED lighting for:

▫ Automotive infotainment

▫ Automotive cluster

▫ Automotive center stack
