TPS389012QDSERQ1 from Texas Instruments, in a WSON-6(1.5x1.5). 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 | SENSE | input | Voltage to be monitored: RESET goes low when SENSE falls below the negative threshold VITN (1.15 V for TPS389012) and goes high when it rises above the positive threshold VITP (1.157 V); the input range is 0 V to 5.5 V. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | MR | input | Manual reset input; driving MR low causes RESET to go low (assert), and the RESET delay runs after MR returns high and SENSE is above VITP. |
| 4 | VDD | power_in | Supply voltage pin, specified at 1.5 V to 5.5 V; good analog practice is to place a 0.1-µF ceramic capacitor close to this pin. |
| 5 | CT | passive | User-adjustable reset delay pin; a ground-referenced capacitor on CT sets the RESET deassertion delay as tPD(r) (s) = CCT (µF) × 1.07 + 25 µs (nom), with CCT limited to 0 to 26 µF. |
| 6 | RESET | output | Open-drain output that is pulled to a low-impedance state when MR is low or SENSE is below VITN, and requires an external pullup resistor (10 kΩ to 1 MΩ per the pin description; 1 kΩ to 1000 kΩ per the Recommended Operating Conditions); RESET current is limited to ±5 mA. |
