IL5851 General Description

NAME VCC PIN 1 Positive supply pin. The voltage on this pin is measured relative to Pin 6 and is supplied from a 150µA current source. This voltage should be regulated to less than 6.0 volts using on external form or regulation. VREF 2 The VREF output provides reference voltage that tracks internal .
