3 / 9 page ![]() - Mar 22-07 RevD SP7616: Low Side LED Driver 2007 Sipex Corporation - - 3 PIN DESCRIPTION PIN NAME DESCRIPTION PIN # VIN Input voltage for the IC. Connect a 1uF decoupling capacitor between this pin and ground. 1 PWM This pin must be held high to enable the output drivers. It can be used for PWM dimming up to 5 kHz. 2 ISET Connect resistor RSET from this pin to ground to set output current. Pulling this pin above the shutdown threshold stated in the Electrical Specifications puts the IC into shutdown mode 3 GND Ground return for LED currents and circuitry of the SP7616 4 LED1- LED4 Connect an LED between each pin and VIN. Current value is controlled by RSET. The current level through each pin is internally matched within 3%. Connect unused channel (s) to GND to save current consumption. 5 - 8 BLOCK DIAGRAM |
