A8502規(guī)格書詳情

A8502屬于集成電路(IC)的LED驅(qū)動(dòng)器。由Allegro MicroSystems制造生產(chǎn)的A8502LED 驅(qū)動(dòng)器器件屬于 LED 驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列,可通過(guò)標(biāo)稱固定電壓的電源為負(fù)載(通常為發(fā)光二極管)提供電流,并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于,這類器件提供較低的反饋電壓(以提高系統(tǒng)能效),而且通常可對(duì)器件工作點(diǎn)進(jìn)行外部控制,可在照明應(yīng)用中用于實(shí)現(xiàn)調(diào)光功能。

描述 Description

The A8502 is a multi-output white LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and two current sinks. The boost converter can drive up to 24 LEDs, 12 LEDs per string, at 120 mA. The LED sinks can be paralleled together to achieve even higher LED currents, up to 240 mA. The A8502 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 120 mA per channel

? Drives up to 12 series LEDs in 2 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 optional 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
