Stresses greater than the Absolute Maximum Ratings specified above may cause permanent damage to the device. These are stress ratings only , and functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum rating s is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. ESD Ratings Symbol Parameter Rating Unit VESD Human-Body Model (HBM), Per AEC-Q100-002 (Note 6) ±2000 V Charged-Device Model (CDM) ±1000 Note: 6. AEC-Q100-002 indicates that HBM stressing shall be accordance with the ANSI/ESDA/JEDEC JS -001 specification.

The maximum source current and drive voltage out of the OUT pin is limited by an internal clamp as well as maximum recommende d junction temperature not exceeding +150°C. OUT voltages greater than 3V are supported but at reduced output currents. As VCC reduces below 6V the maximum output voltage supporting output currents above 10mA also reduces; V CC - VOUT ≥ 3V.

matched, and RS1 and RS2 should be matched. The AL5816Q can be dimmed by PWM signal, it can run at frequencies greater than 200Hz. Figure 3. PWM Dimming Curve of AL5816Q cycle off and on or the junction temperature dropping by +30° C will make the IC turn back on. and/or use a better PCB layout. The device has internal compensation and therefore there’s no need to have any components in the feedback loop.
