DW8501 Linear Constant Current Driver Solution for Automotive Lights & Stage Lights | Datasheet & Design Guide

DW8501 is a wide-input linear constant current LED driver IC launched by DONGWOON ANATECH from South Korea. It operates with input voltage from 5V to 40V and delivers maximum output current up to 1.5A, integrating internal MOSFET and thermal derating protection circuits. Packaged in SOT223?5L and TO252?5L, this device can directly replace AMC7140, AT7316 and other mainstream models pin-to-pin. It is highly suitable for applications sensitive to EMI such as automotive headlights, stage lights and wall washers. Equipped with 0.3V ultra-low dropout voltage and PWM dimming function, it effectively reduces power dissipation in 12V/24V systems and improves overall product reliability.

Core Highlights: 5~40V Wide Input Voltage | Max 1.5A Adjustable Constant Current | 0.3V Low Dropout @300mA | Built-in Thermal Derating Protection | PWM Dimming Support | Low EMI Interference | Pin-to-Pin Replacement for AMC7140 | Dual Package Options: SOT223-5L / TO252-5L
※ Note: The maximum output current of the IC is 1.5A. For high power factor (PF>0.9) flicker-free applications, output current ≤800mA is recommended to achieve optimal heat dissipation and service life. It can run at full 1.5A rating for DC direct drive applications with sufficient heat dissipation.

Product Description: DW8501 is available in two package versions: DW8501-TOJCCT (TO252-5L) and DW8501-SOJHHT (SOT223-5L). As a wide voltage (5~40V) linear LED constant current driver with adjustable output current up to 1.5A, it integrates internal MOSFET and thermal derating protection, supporting 0~100% PWM dimming. Only one external resistor is required for circuit configuration with negligible EMI and maximum efficiency up to 97%. It is widely applied in automotive lamps, stage lights, wall washers, LED light bars and other lighting products, and serves as a perfect pin-to-pin substitute for discontinued models like AMC7140 and AT7316.

TO252-5L封裝的那一款DW8501驅(qū)動(dòng)芯片，是可以完全兼容替換ADDTEK,IML品牌的AMC7140DLGT的,價(jià)格及性能均優(yōu)于A(yíng)MC7140DLGT, 首先DW8501驅(qū)動(dòng)電路和AMC7140DLGT驅(qū)動(dòng)電路的封裝型式都一樣，都是TO252-5L封裝，PKG Size都是TO252-5L(6.5mm*5.5mm*2.3mm), 在輸出驅(qū)動(dòng)電流及驅(qū)動(dòng)能力方面，DW8501大于A(yíng)MC7140，DW8501的驅(qū)動(dòng)電流為1.5A，而AMC7140分兩個(gè)電流檔（AMC7140DLGT電流為200~355mA，主要應(yīng)用于300mA的應(yīng)用產(chǎn)品，AMC7140DLGT-A的驅(qū)動(dòng)電流范圍為350~600mA，主要應(yīng)用于500mA的應(yīng)用產(chǎn)品），所以從驅(qū)動(dòng)電流及驅(qū)動(dòng)能力上，DW8501優(yōu)于A(yíng)MC7140，從輸出反向電流來(lái)看，AMC7140驅(qū)動(dòng)的反向電流是5mA，而DW8501的反向電流只有1.5mA，反向電流更小了，所以DW8501比AMC7140更穩(wěn)定。因?yàn)榉聪螂娏髋c芯片的溫度有著密切的關(guān)系，因?yàn)榉聪螂娏髟酱?，溫升就越高? 再來(lái)看AMC7140和DW8501的PWM調(diào)光特性，首先大家都可以實(shí)現(xiàn)0~100%的無(wú)級(jí)PWM調(diào)光，還有模擬調(diào)光，但是在雙方都不做PWM調(diào)光或模擬調(diào)光應(yīng)用時(shí)，AMC7140需要增加一個(gè)外圍元器件LDO到EN引腳，而DW8501是不需要的，輸入VIN可以直接接到EN調(diào)光腳，因?yàn)锳MC7140的EN PIN電壓只耐壓到13.2V，而DW8501的EN PIN電壓可達(dá)40V
