BCR 320U E6327 / BCR 321U E6327 LED Driver 1 LED Driver 1.1 Features
• LED drive current preset to 10 mA • Continuous output current up to 250 mA with an external resistor • Easy paralleling of drivers to increase current • Supply voltage up to 25 V • Low side current control • Digital PWM input up to 10 kHz frequency (BCR 321U E6327) SC74-3D • Up to 1 W power dissipation in a small SC74 package • Negative thermal coefficient of -0.2 %/K reduces output current at higher temperatures • RoHS compliant (Pb-free) package • Automotive qualified according AEC Q101
1.2 Applications
• Architectural LED lighting • Channel letters for advertising, LED strips for decorative lighting • Retail lighting in fridge, freezer case and vending machines • Emergency lighting (e.g. steps lighting, exit way signs etc.)
1.3 General Description
The BCR 320U E6327 / BCR 321U E6327 provides a low-cost solution for driving 0.5 W LEDs with a typical LED current of 150 mA to 200 mA. Internal breakdown voltage is higher than 16 V which is the maximum voltage the LED driver can sustain when the output is directly connected to supply voltage. The BCR 320U E6327 / BCR 321U E6327 can be operated with a supply voltage of more than 16 V considering the voltage drop of the LED load which reduces the output voltage to the maximum rating of the driver. The enable pin of BCR 320U E6327 can withstand a maximum voltage of 25 V which can be increased adding a series resistor in front of the enable pin reducing the voltage at the enable pin below 25 V. The digital input pin of BCR 321U E6327 allows dimming via a micro controller with frequencies up to 10 kHz. A reduction of the output current at higher temperatures is the result of the negative temperature coefficient of - 0.2 %/K of the LED driver. With no need for additional external components like inductors, capacitors and free wheeling diodes, the BCR 320U E6327 / BCR 321U E6327 LED drivers are a cost-efficient and PCB-area saving solution for driving 0.5 W LEDs.
