LP5024規(guī)格書詳情

LP5024屬于集成電路(IC)的LED驅(qū)動(dòng)器。由德州儀器制造生產(chǎn)的LP5024LED 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??蓪ζ骷ぷ鼽c(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。

1 Features

? Operating voltage range:

– VCC range: 2.7V to 5.5V

– EN, SDA, and SCL pins compatible with

1.8V, 3.3V, and 5V power rails

– Output maximum voltage: 6V

? 24 constant-current sinks with high precision

– 25.5mA maximum per channel with VCC in full

range

– 35mA maximum per channel when VCC ≥ 3.3V

– Device-to-device error: ±7%; channel-tochannel

error: ±7%

? Ultralow quiescent current:

– Shutdown mode: 1μA (maximum) with EN low

– Power saving mode: 10μA (typical) with EN

high and all LEDs off for > 30ms

? Integrated 12-bit, 29kHz PWM generator for each

channel:

– Independent color-mixing register per channel

– Independent brightness-control register per

RGB LED module

– Optional logarithmic- or linear-scale brightness

control

– Integrated 3-phase PWM-shifting scheme

? 3 programmable banks (R, G, B) for easy software

control of each color

? 2 external hardware address pins allow connecting

up to 4 devices

? Broadcast slave address allows configuring

multiple devices simultaneously

? Auto-increment allows writing or reading

consecutive registers within one transmission

? Up to 400kHz fast-mode I2C speed

2 Applications

LED lighting, indicator lights, and fun lights for:

? Smart speaker (with voice assistant)

? Smart home appliances

? Video doorbell

? Electronic smart lock

? Smoke and heat detector

? STB and DVR

? Smart router

? Handheld device

3 Description

In smart homes and other applications that use

human-machine-interaction, high-performance RGB

LED drivers are required. LED animation effects

such as flashing, breathing, and chasing greatly

improve user experience, and minimal system noise

is essential.

The LP50xx device is an 18- or 24-channel constant

current sink LED driver. The LP50xx device includes

integrated color mixing and brightness control,

and pre-configuration simplifies the software coding

process. Integrated 12-bit, 29kHz PWM generators for

each channel enable smooth, vivid color for LEDs,

and eliminate audible noise.
