This is required to force iC-HTP leaving standby mode and starting normal operation, as the pin includes an internal pull-down resistor. Laser channel enabling Setting pins EC1, EC2 to hi enables the corresponding channels. In order to ensure safe operation of iC-HTP, several events automatically disable both output chan- nels: • Pins INS/WKR or EMC left unconnected (IN- SOPEN, EMCOPEN), iC-HTP enters error mode and the laser channels cannot be enabled. • Supply power-down either at VB (PDOVBLx) or VDD (PDOVDD), the laser channels are uncondi- tionally disabled during the power down event. • Overcurrent (OVC) or overtemperature (OVT), laser channels are switched off. Cycling pins EC1, EC2 or a power-up is required to switch on the laser again. |
