Description
The A8501 is a multioutput WLED/RGB driver for backlighting medium-size displays. The A8501 integrates a boost converter and four 100 mA current sinks. LED channels can be tied together for up to 400 mA sink capability. It can work from a single power supply of 8 to 21 V and withstand up to 40 V. The boost converter is a constant frequency, current-mode converter
Features and Benefits
? 600 kHz to 2.2 MHz switching frequency—ability to operate above the AM band
? Internal bias supply for single-supply operation (VIN = 8 to 21 V)
? Boost converter with integrated 40 V DMOS switch and OVP–load-dump protection
? 3.5 μA shutdown current—limits battery drain
? Active current sharing between LED strings for 0.8 current matching and 0.7 accuracy
? Drive up to 9 series LEDs in 4 parallel strings, 36 LEDs maximum (Vf = 3.5 V, If = 100 mA)
? LED sinks rated for 100 mA each (400 mA total)
? PWM dimming with LED PWM duty cycle control
? 4000:1 dimming range
? Extensive fault mode protection schemes:
? Shorted LED protection against misconnected loads—with true output disconnect
? Open LED disconnect protects against LED failures
? External thermistor sensing to limit LED temperature
? Output overvoltage protection (OVP): 19.5 V default can be adjusted as high as 38 V
? Open Schottky and open OVP resistor protection against external component failure
? Input under- and overvoltage protection (UVLO and OVLO) against VIN variation
? Boost current limit, output short circuit limit, overtemperature protection (OTP), and soft start
Applications include:
? GPS navigation systems
? Automotive infotainment
? Back-up camera displays
? Cluster backlighting
? Portable DVD players
? Industrial LCD displays
