TPS3840DL41DBVRQ1 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 | output | Active-low, open-drain reset output. Asserted low when VDD falls below the negative voltage threshold (VIT- = 4.1 V typ.) or when MR is pulled to a logic low. Deasserts (high-Z) after the programmed delay time (tD) once VDD rises above VIT+ (VIT- + 200 mV) and MR is released. Requires an external pull-up resistor. |
| 2 | VDD | power_in | Input supply voltage and monitored rail. Operating range 1.5 V to 10 V; monitored against VIT- = 4.1 V typical with 200 mV hysteresis. |
| 3 | GND | power_in | Device ground reference. |
| 4 | MR | input | Manual Reset input, active low. Pull below VMR_L to force RESET asserted; float or pull above VMR_H for normal operation. Internal glitch immunity. May be left floating (NC) when not used. |
| 5 | CT | passive | Capacitor Time Delay pin. Connect an external capacitor between CT and GND to program the reset delay time tD from ~50 µs (no cap) up to ~6.2 s with a 10 µF capacitor. Leave floating for fastest reset. |
