TPS3840DL49DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | tri_state | Open-drain active-low reset output that asserts (pulls low) when MR pin voltage is below 600mV or VDD drops below VIT- of 4.9V, and releases to high-impedance state after programmable delay tD when monitoring voltage returns above 4.9V plus 200mV hysteresis. |
| 2 | VDD | power_in | Supply voltage input rated 1.5V to 10V; device monitors this voltage and triggers reset when it drops below VIT- threshold of 4.9V. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Manual reset active-low input with internal 100kΩ pull-up; pulling below VMR_L of 600mV forces reset output assertion, which is released after delay tD when MR returns above VMR_H or floats. |
| 5 | CT | passive | External capacitor connection for programming reset delay time tD from 50µs minimum (floating) to 6.2s maximum (10µF capacitor), with recommended maximum capacitor value of 10µF and internal resistance RCT of 350kΩ to 650kΩ. |
