SLVSE46A November 2017 – January 2018 TPS65680
TPS65680 provides two GSP (Gate Start Pulse), one GCP (Gate Clear Pulse), and two GGP (General Purpose) high-voltage outputs intended for driving control signals of the GIP circuitry. All outputs are parametrically identical. GSP channels drive to VGH and VGL2. GCP and GGP channels drive to VGH and VGL2. All channels support High, Low, and HiZ state.
At power-up, all HV outputs are in HiZ state and remain in this state until VGH, VGL1 and VGL2 are powered up. Then the outputs are released to the programmed output state as defined in register and remain in this state until the sequencer takes control after the programmable EN_DLY timer in register expired. During panel-discharge, the outputs can be configured to be in Low or High state, separately for DISCHARGE STEP1 and DISCHARGE STEP2 using the respective bits of the and registers.
