TPS3840PH45DBVR 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 reset output; asserts high when VDD drops below VIT- (4.5V) or MR is pulled low, and remains high for reset delay time tD before releasing to logic low. |
| 2 | VDD | power_in | Power supply input voltage (1.5V to 10V); monitored by internal comparator for undervoltage condition. |
| 3 | GND | power_in | Ground reference return. |
| 4 | MR | input | Manual reset input active low; pulling below 600mV triggers reset output independent of VDD level; leave floating or above 0.7×VDD for normal VDD-monitored operation. |
| 5 | CT | passive | Timing capacitor input; external capacitor between this pin and ground programs reset delay time from 50µs (floating) to 6.2s (10µF). |
