TPS389033DSER 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 monitoring input; RESET output asserts when SENSE voltage falls below VITN and deasserts when SENSE voltage rises above VITP. |
| 2 | GND | power_in | Ground reference. |
| 3 | MR | input | Manual reset input; driving MR low causes RESET to assert. |
| 4 | VDD | power_in | Supply voltage input rated 1.5 V to 5.5 V nominal; place 0.1-µF ceramic capacitor close to this pin for analog design. |
| 5 | CT | passive | Capacitor connection pin for user-adjustable RESET delay time; delay = CCT (µF) × 1.07 + 25 µs (nominal). |
| 6 | RESET | tri_state | Open-drain output asserts low when MR pin is driven low or SENSE voltage falls below VITN; deasserts after delay period when both MR is high and SENSE is above VITP; use pullup resistor 10 kΩ to 1 MΩ. |
