11 / 133 page Pin Symbol Function 32 TM1 Test mode 1: Not for customer use. Leave this pin floating in the application. 33 MPS Microcontroller programming mode Connect this pin to ground for normal operation in the application. Optionally the pin can be used for microcontroller programming purposes, see Application information. 34 IOVDD I/O supply voltage: Connect this pin to the I/O supply voltage of the microcontroller. Add a decoupling capacitor. 35 SYNCO Synchronization output: Optional: Connect this pin to an external switch-mode post-regulator synchronization input. This pin delivers the internal switching frequency signal, either in phase or shifted by 180°, depending on the settings via SPI. The switch-mode post-regulator synchronizes to the rising edge. If this pin is not used, then leave it floating. 36 SYNCI Synchronization input: Connect this pin to an optional external synchronization signal to synchronize the switching of the internal switch-mode regulators. The feature needs to be enabled via SPI. If the pin is not used, then leave it floating. 37 SDO Serial peripheral interface, signal data output: SPI signalling port; connect this pin to the SPI port "data input" of the microcontroller to send status information during SPI communication. 38 SDI Serial peripheral interface, signal data input: SPI signalling port; connect this pin to the SPI port "data input" of the microcontroller to receive status information during SPI communication. 39 SCL Serial peripheral interface, signal clock input: SPI signalling port; connect this pin to the SPI port "clock" of the microcontroller to clock the device for SPI communication. 40 SCS Serial peripheral interface, signal chip select: SPI signalling port; connect this pin to the SPI port "chip select" of the microcontroller to address the device for SPI communication. 41 ROT Reset output: Open drain structure with internal pull up resistor. "Low" indicates a reset event for the microcontroller. Connect this pin to the microcontroller reset input. 42 INT Interrupt output: OPTIREG™ PMIC TLF30681QVS01 Power management IC Pin configuration Datasheet 11 Rev. 1.0 2020-04-08 |
