Shutdown Mode
Upon the application of a logic low shutdown signal, the
entire IC converts to micropower shutdown mode where
V
CC
supply current reduces to less than 0.3
μ
A typical. The
shutdown function features the data retention of the cur-
rent PWM1 and PWM2 codes so that upon release from a
shutdown condition, these states are reinstated. This is a
functional difference in comparison to the half-scale preset
for both PWM1 and PWM2 outputs upon power-up.
