AL8843Q Functional Block Diagram
SET SW 3 7, 8 6 VIN VDD 4.5V AL8843Q Current Generator 4.5V_Drv Monitor Comp BG & Ref Hysteresis Logic & Reference Control PWM Driver PWM/DC PWM OTP CTRL Dimming OTP 5 1, 2 GND
Absolute Maximum Ratings
(Note 5)
Symbol Parameter Rating Unit
VIN Input Voltage -0.3 to +42 V VSW, VSET Voltage at SW pin and SET Pin -0.3 to +42 V VCTRL CTRL Pin Input Voltage -0.3 to +6 V TJ Operating Junction Temperature -40 to +150 °C TSTG Storage Temperature Range -65 to +150 °C TLEAD Lead Temperature (Soldering, 10s) +300 °C Note: 5. Stresses greater than those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings for extended periods can affect device reliability.
