DLPS037F October 2014 – June 2021 DLPC900
POSENSE and PWRGOOD are active high signals that are generated by an external voltage monitor circuit. POSENSE must only be driven active high when all the controller and DMD supply voltages have reached 90% of their specified minimum voltage. The DLPC900 is safe to exit its RESET state once PWRGOOD is driven high. PWRGOOD has no impact on operation for 60 ms after rising edge of POSENSE.
