Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3837K33DBVR from Texas Instruments, in a SOT-23-5. 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 | CT | input | Capacitor time delay pin: connect to GND to set the reset delay to 10 ms, or connect to VDD to set it to 200 ms. |
| 2 | GND | power_in | Ground reference for the device; all voltages are specified with respect to GND. |
| 3 | MR | input | Manual reset input: a logic-low on MR activates RESET, and if unused it should be connected to VDD to minimize current consumption. |
| 4 | RESET | output | Active-high push-pull reset output that goes high when VDD falls below VIT or MR is driven low, and returns low after the reset delay tD once VDD exceeds VIT plus VHYS and MR is high. |
| 5 | VDD | power_in | Input supply voltage that the device monitors; recommended supply range is 1.6 V to 6 V. |
