JAJSDF6A February 2017 – September 2021 TPL5110-Q1
PRODUCTION DATA
During start-up, after POR, the TPL5110-Q1 executes a one-time measurement of the resistance attached to the DELAY/M_DRV pin in order to determine the desired time interval for DRV. This measurement interval is tR_EXT. During this measurement a constant current is temporarily flowing into REXT.
Once the reading of the external resistance is completed the TPL5110-Q1 enters automatically in one of the 2 modes according to the EN/ONE_SHOT value. The EN/ONE_SHOT pin must be hard wired to GND or VDD according to the required mode of operation.
