TPS3106E09DBVR

Texas Instruments · Monitors & Reset Circuits · SOT-23-6

TPS3106E09DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RSTVDD output Active-low open-drain reset output whose logic level depends only on the voltage at VDD and the status of MR.
2 GND power_in Ground.
3 MR input Manual-reset input; pull low to force a reset, RESET stays low while MR is low and for the time-out period after MR goes high, leave unconnected or connect to VDD when unused (absolute max -0.3 V to VDD + 0.3 V).
4 SENSE input A reset is asserted if the voltage at SENSE is lower than 0.551 V; connect to VDD if unused.
5 RSTSENSE output Active-low open-drain reset output whose logic level depends only on the voltage at SENSE and the status of MR.
6 VDD power_in Supply voltage that powers the device and monitors its own voltage, recommended 0.9 V to 3.6 V.
