TPS389030DSER 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 asserts when SENSE falls below negative threshold VITN and deasserts when SENSE rises above positive threshold VITP. |
| 2 | GND | power_in | Ground reference. |
| 3 | MR | input | Manual reset input; driving this pin low causes RESET to assert (go low). |
| 4 | VDD | power_in | Supply voltage input rated 1.5 V to 5.5 V; place 0.1 µF ceramic capacitor close to this pin per good analog design practice. |
| 5 | CT | passive | Capacitor timing pin for user-adjustable RESET delay; connect to ground-referenced capacitor with delay time calculated as tPD(r) (sec) = CCT (µF) × 1.07 + 25 µs nominal. |
| 6 | RESET | tri_state | Open-drain reset output; driven low when MR is low or SENSE voltage is below VITN, remains low for programmable delay period after MR rises to high and SENSE exceeds VITP, requires 10 kΩ to 1 MΩ pullup resistor. |
