Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3840PH30DBVR 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 | RESET | output | High-level active output reset signal activated when MR pin is pulled to logic low or VDD falls below negative threshold (VIT-), released after reset delay time (tD) when MR returns high and VDD rises above VIT+. |
| 2 | VDD | power_in | Input power supply voltage monitored by TPS3840; specified operating range 1.5V to 10V. |
| 3 | GND | power_in | Ground reference connection for device and internal circuits. |
| 4 | MR | input | Manual reset active-low input; pulling below 600mV threshold (VMR_L) activates reset output, released when pulled above 0.7×VDD (VMR_H) after programmed delay time (tD); can be left floating. |
| 5 | CT | passive | Capacitor timing pin providing user-programmable reset delay time; connect external capacitor (0.01µF to 10µF) to set delay from 5.8ms to 6.2s, or leave floating for minimum fixed delay of 50µs. |
